Rotface 25 is dead. Took 3 attempts last night. We found that the secret to killing him efficiently was to abuse the Rotface tank (me), magnificently.
We ran in to the issue that rotface would begin to cast slime spray when everyone scattered for volatile ooze explosion. Because of the long range on the spray, and the fact that I had taken Rotface to the side, this lead to upwards of 50% of the raid finding themselves in the blast radius. After two wipes to this, I got kinda frustrated. So as the next ooze explosion went off, I just popped Divine Protection and stood there. And took no damage. Every ooze missed me.
I wasn't so lucky the second explosion, and when I reached for my cooldown, I realized that I had traded in my 4 piece t9, and it was on cooldown. So I quickly took stock of options, and hit the only defensive cooldown I had up. My Corroded Skeleton Key. This time I was not so lucky, I took about 7 slimes to the crown, and barely walked away, thanks to some pretty amazing heals.
The third explosion was much less harrowing, as Divine Protection was available again. At that point, we had entered the 6 second infection "oh shit" zone. At that point somehow a second big ooze spawned, and took out the Co-Tank. The Professional Hunter and Shameless Boomkin immediately started attempting to kite them as we blew hero and tried to outrun the fact that the bottom was falling out beneath our feet. With about 5 people down, Rotface hit the ground. There was no tanking loot to be had, but we did get the blood out to our Charter Ret Pally, who made the first Shadow's Edge in the guild.
We proceeded to go and attempt Professor Putricide. We lost one attempt to the Co-Tank, using a completely stock ui for this fight, not having bars spawn for the abom. We lost two attempts to glitched oozes trying to target the Co-Tank in the abom, and thus burning all their snare time trying to pick a target. The most annoying however, was the attempt we lost to our resto shaman who DCed while autorunning up the hall. Grrrrr...
Anyways, in the six non fucked attempts we got in, we got him into phase three twice, with our best attempt hitting the hard enrage at 28%. I feel confident that we'll down him next week.
