That was the first room where I said "fuck this". I was running around as a mid-rank, half-assed Mystic Knight (was leveling the vocation just to be able to dragonforge my Fighter's gear much easier). I couldn't kill shit before the room was filled with maelstrom and I was bouncing for 30s before dying (after everyone else had run in and died to the three worgs that appear as well).
Switched back to MA, and proceeded to dice the hell out of the Sorcerers before they could cast anything, then ran back into the hall making all of the pawns follow. The worgs got utterly shredded with Ricochet, and afterwards it was cheesing the Gorecyclops with Sixfold.
I honestly have to wonder; seeing as how the MA went from zero (other than Ur dragon) to hero with this expansion, is it now the most versatile class? Ancient Ogres are literally dead in seconds now, undead really don't do anything (Heaven's Key), Eliminators get burnt to death by Explosive + Immolation + Wind spam and Gorecyclops get exploited with Sixfold.
The only class that I can see that can compete without too many problems--due to being able to exploit elemental weaknesses--would be the Sorcerer. The MK could as well I suppose, but I don't like the way the cannon works, and it's probably just me, but the shield countering seems too infrequent to really matter. The other three Strider clone classes are all physical until you get a lucky drop (although they can all do Holy damage), and while the Fighter can output impressive damage and has survivability, it has no range and I have no idea how it is supposed to handle a Gorecyclops. The Warrior is a "fun" class in vanilla, and I could see it doing "okay" on many things in BBI, but I can also see it being incredibly frustrating on just as many others.
