Angry Grimace
Two cannibals are eating a clown. One turns to the other and says "does something taste funny to you?"
I'm jealous of you stealth players. Slabhide I could get down to around 2:35 at the absolute fastest (2:50 or so was my average across all runs).
If everything aligns perfectly I could get through VP pulling only the two mobs on the first bridge and the three before the bridge to the first boss. I was able to scoot past everything else by running along the outer edges of most ramps (and the inner edge when the mobs moved just right for the third group down the large spiral ramp).
Rivendare is a bit of a turd. Not much can be done to speed things up. I can typically dodge all enemies in the gauntlet but it still requires killing each ziggarut boss or whatever and then running through the inside to round up the five fellows inside before killing them and heading to the next. And the whole area with the abominations is fairly slow, too. I really hope I get that mount pretty soon because it's definitely the worst of these last dungeon runs I had left. Suppose it's on par with Heroic ZA as that took me around six minutes for both bosses (and then hearthed out) but I have both of those so I don't have to concern myself there any longer either.
I got Rivendare's mount in 3.0.8 when there was a bug that let you just walk straight to Baron Rivendare.
