Actually, I think he's slightly off. I don't think it's that everyone is bad, it's that they've all become lazy. Oculus required some extra coordination and planning, and everyone just want to charge in and aoe everything in Wrath.

I don't think this dungeon would have been at all out of place in BC, the trash packs would have seemed completely normal for those dungeons. You just have to take the time and effort to control the mobs.

The only thing I ever hated was the drakes, and they fixed that with scaling. It's very irritating to get all this gear and then have a gimmick fight where it has no impact. I don't think they really needed to scale it more at this point, but I don't really object to that part. Making the rest of the changes seems like overkill, though. I hope things like standing in the Mage Lord Arcane Explosion still one shot people, there are certain things you need to be able to do or you should die. When everyone acts in a competent manner, and is willing to take a few extra minutes to properly drop the trash (kill them one at a time, if you just aoe they drop those stupid icicles like crazy and you get overwhelmed) and avoid/don't stand in fire/frost/lightning/things that are bad then it can be incredibly fun.
