Actually, the problem is that, instead of putting a 25-man entry level raid, they simply dropped the attunements. SSC & TK were never meant to be a 25-man entry raid. Gruul Lair was, except that it had only 2 bosses, with so little loot, people had to do Karazhan to get stuff. Adding more loot to Heroic instances (and soon, more badge options) is still avoiding the problem.

People are asking for SSC to be nerfed, because there isn't any 25-man instance that they can do. That's what most of everybody on the "casual side" says. They know it. But, instead of fixing it "now", they're going to fix it in WotLK.
If you simply reinstate the attunements, yes. If you reinstate attunements (or a lesser form of them in TK's case), and add an entry 25-man, it would go a long way. Specially if the 25-man would provide an alternate attunement to SSC, so you can run an heroic & Kara to get in SSC, or kill the "Ragnaros" of the entry raid.

a) You were most likely Alliance then. The guy you responded to probably Horde. Especially in a fight where BoS for dps/healers and BoK for the tank make such an immense, that makes your post silly to begin with.
b) Full T2 gear at Broodlord compared to people who reach him in blue/MC gear ... I won't comment any further on that. If you even had a TF for some extra threat, you should quickly delete your post.

And to get a bit back on track here. there is NO difficult fight in TBC (after nurfs) other then Kael. Anything else does not require any form of serious coordination, dps or silly raid stacking. Kael is a bit different as the encounter requires both coordination and fairly high dps. The dps issue was kinda nurfed with arena weapons and karaz/t4/t5 level gear being quite powerful, compared to the gear you obtain from Kael onwards.
Anyway, I agree that Kael is too hard for casual guilds. I figured he would be nurfed by now. Extended the weapon phase and the respawn of the advisors-phase by 10-15s each would make the whole thing dramatically easier and also bring the different phases of the fight in line, as p1 is a joke, p2/p3 is hard and after that it's rather smooth sailing.

Before that, I really don't see the point. The stuff is not hard. I know several guilds raiding three days per week that reached Kael easily. It requires some coordination and a few people that put in some work to learn the encounters from videos and explain stuff, but if you want to do something with a group of 30-45 people, you WILL need someone doing some amount of work. That is the same with any RL activity that involves that many people. Or do you think baseball/soccer/basketball leagues run themself and your team's coach only shows up for practice units without doing anything at all outside of that time?

If you think you should experience high end raiding content with two raiding days per week or less, imho you are in the wrong game genre. MMORPGs are not exactly known for requiring a minimum of invested time to complete.

I quit the game before I saw as much raiding content in TBC as in vanilla and I won't comment individual fights. However, if what kaib says about coordination is true, I'm not surprised. It's not that hard to grasp that coordinating 25 is easier than coordinating 40 or more and I believe that if Blizzard wants to make really challenging raid encounters 25 players per raid won't be enough.

I think people not having access to raiding content is certainly not a case of mono-causality. Something along the lines of "stuff is too hard" and "raiding takes too long" won't cut it. Hardcore vs casual is frowned upon for a reason here. But quite obviously raiding problems are not only the result of encounter tuning.

*rant*
I remember when AQ 40 was opened on my server we were just starting at chromaggus and it took us a couple of nights (3-4? but we never dedicated a full night to him since we were still farming MC) to down him. Just having the option of doing something argueably more efficient (-> go kill Skeram) was causing quite a bit of unrest for us. If we hadn't been raiding for a few month by then this might have well had a bigger impact on us. It was similar when we had the choice between Anub'rekhan, Razuvious, Ouro or C'thun and I think making a bad choice back then affected our motivation (and thus participation) in the long run and eventually killed our progression in Nax(in combination with the pvp patch). Getting people to farm resistance items and consumeables wasn't trivial either, since we always had trouble findind good recruits on our server, so we couldn't just say: "farm or leave".
*rant off*

I think making players go from 10 to (nontrivial... in a sense of "you actually need 25 people awake and at their keyboards") 25 man content and then offer them choices and basically demand consumeable use almost at the same time is, combined, just a bit over the top not only for the average joe raider but for most leaders as well. I think it would be better to face those different challenges over time and not all at once right when you start 25-man raiding. (As I mentioned earlier I even think its a bad idea to have a single PvE progression path that forces you to go from 10 to 25 man raiding ever.)

Besides Kael there isn't much to stop you from going BT/Hyjal once you sort these issues out. Additionally I think some people are mixing things up here. Wishing for a good introduction to 25 man raiding does not mean the current raiding is generally too hard. Actually it lacks a proper increase in difficulty at times (after Kael).

Just to emphasize:
Consumeable use in itself is not necessary a problem.
Difficulty in itself is not necessary a problem.
Being offerend choices is not necessary a problem.
Going from 10 man to 25 man is (in my opinion) a problem.
I think all of these combined (and I'm sure to have missed something) right at the start of BC 25-man raiding create huge problems for starting raiders.

I assume by "consumable use", you're referring to mana potions and ironshield potions, because the remainder of it is manageable by comparison. Blizzard needs to take a serious look at these, because they really don't add to the game in a raid environment, and really add to the "grindy" feel that I think burns a lot of people out. Most people who raid are at least a little bit competitive, and part of being competitive is feeling like you're giving 100% to the effort. Obviously, the more Blizzard does to increase the amount of time investment involved in giving 100%, the more they're going to alienate the semi-hardcore crowd that (and this is totally speculation) makes up the bulk of the end game raiding crowd. And I say this because it's something I hear over and over again from friends of mine who play the game and stopped raiding, or are playing the game but are feeling burnt on it. Healers in particular. They just don't see why they should have to put up with long hours in raids followed by long hours farming just to feel like they're doing the best they can and not short-changing their guild.

The staff buff makes you immune to stun, how is that You Lose?

I'm only just beginning Hyjal and BT so I haven't seen the wonders of encounters like Mother S yet, but so far there haven't been any situations that aren't in the player's hands whether you win or you lose.

I agree whole-heartedly with that last sentence, but I would go so far as to replace 'guild' with 'raid.' My position is probably a bit of a rare one on these boards: I'm not in a hardcore raiding guild; I'm in a very *very* casual one. We raid approximately whenever the hell we feel like it, more often than not spreading it out and pugging Kara with our alts and mains and whoever LFG turns up.

When I raid on my healer, no matter who else is in my group, if I think we're going to kill the boss that attempt or not, I will always use mana oils and pot and elixir up (mana pots are the big one here) if for no other reason than I will be damned before an attempt falls short because of me being greedy with my consumables. If I screw up a heal (which is pretty rare [shameless]), fine, my fault, it won't happen again. But if I go oom because I didn't pot early or often enough, that's inexcusable.
