No gimped version this time around. As far as we can tell, this is close to the one Blizzard wants in the game. Very intense, very dependant on people doing what they're supposed to.
Gurg et al can weigh in on the specifics. I'm just here to post this:

GurgNote: This was a lot of fun, and satisfying to pull off. On the attempt prior to the kill, we had the heartbreaking equivalent of an 0.1% wipe (for the Visc-savvy, missed the final shatter by maybe a second). That hurt, but at least this is definitely repeatable. It's harder than Huhuran and I'm not sure we'll ever be able to do Visc with a thrown-together group of whoever happens to be available for the raid the way we can Huhuran and even Emps to some extent, nor without heavy consumables use. It definitely isn't parallel to Huhuran, and for Alliance guilds blows Emps out of the water. I enjoyed the challenge, and I actually quite like all the loot on Visc's loot table, but there's some risk:reward tuning still to be done.
