Onyxia barely deals melee damage as it is, her damage range might cover the +50% on crushings already.

This was posted for what its worth...

CMs clarified it further, final word is in on boss scaling. It's treated at an individual level.

Sort of an odd way to do it but... meh. At least the Devs passed down that the bosses should not be doing anymore dmg than before, so as long as you replace your gear to the same pre-TBC levels of mitigation you should be ok.

Hmm... that last sentence of the second paragraph could be intepreted as "The only thing scaling is the bosses' mitigation vs each player's incoming damage", with nothing to do with your mitigation levels vs the boss' damage.

I can't imagine, for example, hitting 70% mitigation (25kish? armor) for the purpose of Patchwerk. (Hi Patch, long time no thread). I believe THAT was the main thing people wanted cleared up... Admittedly, the first sentence of that same paragraph leads me to believe this is the case we're looking at, even though it wasn't explicitly stated.

Some guys need to trot lv70 tanks with decent lv70 gears down there to see what happens... not because he drops anything good, but to quench this ridiculous curiousity I have.

That's doable by druids. There's blue stuff in TBC that allows a druid to get to over 4500 base ac. In Dire Bear form with appropriate talents...

That REALLY doesn't make sense unless it was changed recently, because if that was the case, a single level 60 pulling ppl through uldaman would have made Archaedes absolutly invulnerable to the group, which wasn't the case.

Uldaman is not a raid instance. The boss mobs in there do not scale. (I think?) And even if it *did* scale, the boss's HP and dmg are static, only the glancing blows, hit%, and resist rates are scaling, according to the devs.

You are also misreading what the CM posted. The scaling is done on an individual level.
If a level 60 and a level 70 zone into Onyxia's Lair, the lvl 70 will experience glancing blows and resists as though Ony were lvl 73. The lvl 60 will experience the same, but as at a rate consistent with Ony being a lvl 63 mob.

Archaedas used to be flagged as a boss - it's just a setting - it doesn't vary at all based on what type of zone it is. Another example of this was Drakkisath, who was initially flagged as a boss. If it's flagged as boss, e.g. no level listed, then it's always +3 your level for the things detailed in Netharea's post. Like was said a while back, this was done so previous content isn't completely trivialized by expansions(though obviously with item inflation it will be to an extent). I can't really say I agree with the reasoning, but I can understand some of the implications of people being able to 2-man or even solo a mob like Onyxia or other old raid bosses due to having 75% mitigation, extreme amounts of Dodge/Parry/Block, as well as resisting most spells.

So, a couple of months later, Digo was right.
