Onomatopeizator

Let's put it this way: I'm on Kael atm. I still have a chance, remote or not, to see Kil'jaeden. I have absolutely zero chance to see Kael v1, old Solarian and a few others.
A few people have already said it in this thread, but I'll repeat: nerfing bosses screws over people that have started raiding later, can't find a good guild with raiding times that suit them, etc., and still want to see as much content as they can. The nerfs are not new and I've come to terms with not seeing the v1 of most bosses - but sometimes, they are going too far. Take Solarian, who was basically replaced by a body double. Take Magtheridon, if all the rumored changes are true.

About the changes: Removing trash and adding shortcuts to final bosses is a good idea. I've seen a few guilds that raid 2-4 times a week and/or have a large roster, and don't have enough training time on the end bosses to progress(my current guild, for one). That could be remedied by being more efficient, but many people treat farm content as some sort of holiday, and motivating them to clear it faster is harder than getting them to do good on new bosses.
Second, more 10-man content! Organizing 25-man raids is a big problem with truly casual people (those that can raid one week, but not at all the other), since the amount of people turning up for raids will vary greatly. And "friends&family" guilds don't really reach a size that would allow them to go Gruul.

Ending, people already said, the "casual" (and to a lesser extent "hardcore") pretty much means different things to each of us. So instead of saying what this/that group wants, please just say what -you- want.

Added: In the "Tabula Raider" thread iirc, it was suggested that a spectator mode would be fun to have for raids. Something like that would go a long way to pleasing people that want to see all content because they are lore freaks, but don't care for raiding at all.
