It's inexplicable, really. We've been trying for weeks to take Rotface down, bringing him as low as 3%, but never quite making it before being overwhelmed. Then, last night, everything just clicked - slime pools were circumnavigated, oozes were kited expertly, and everyone got the hell out of the way when they exploded. Fully expecting to spend at least an hour on the fight, we proceeded to one-shot it. *shrug*
What this meant, of course, was that as soon as we headed over and killed Festergut (who is essentially on farm status now - though he refuses to acquiesce to my demands for footwear), we would be facing Putricide for the first time. It's an interesting fight, and frankly seems less fiddly than the ooze-wrangling of Rotface. There are, in fact, oozes to wrangle, but dealing with them is wholly reliant upon proper player movement and sufficient dps, rather than a somewhat unpredictable pathing A.I.
We made solid progress as we learned the fight, bringing the good Doctor down to ~50% on our last attempt. It will be interesting to see how we handle phase 3; on one hand, no more gas clouds or volatile oozes to deal with; on the other, the tanks and healers will have more to worry about...
In other news, I've made the switch to a Marksmanship spec - having acquired the two-piece T10 bonus, its inherent potential for abuse in conjunction with a properly-timed serpent sting and chimera shots made this a foregone conclusion, and my dps last night definitively bore the assumption out.
