With 3.1 going live today, it's time to have a real discussion thread on Ulduar. Post your general experiences related to the instance here.
Looks like a likely kill order (based on location per
http://www.stratfu.com/tools/ulduar-map/ ) will be:
Flame Leviathan
Ignis
Razorscale
XT-002
Iron Council
Kologarn
And then it becomes a bit more nonlinear, with the option to take down the Watchers in virtually any order, excepting Auriaya before Freya.
Hodir
Thorim
Auriaya
Freya
Mimiron
Then finally:
Vezax
Yogg-Saron
Algalon
It's hard to really have an impression on difficulty level, since there's no way to know whether our experiences on the PTRs reflect the final tuning. I suppose we find out, for the earliest-raiding guilds, in 3-6 hours.
