The first 4 were pretty easy, I can see Stone Guard being a nice block to pugs however.
Elegon was nicely tuned. DPS check was tight for normal modes and I think a lot of guilds expecting to faceroll normal modes will come to a nice halt on this one. Requires a fair bit of strat tuning, but was definitely rewarding to kill.
Will of the Emperor doesn't seem too bad thus far. Spent 30mins on it last night; a lot of repetition but mainly revolves around learning the Devastating Combo attacks and being able to avoid them every time, after that I don't see it being an issue. The adds didn't pose much of an issue throughout the fight.
