A face only a father could love...
The PlagueWorks section of Icecrown Citadel is dominated by Professor Putricide and his two "children", Rotface and Festergut. Consistent with the spirit of Icecrown, The Plagueworks provide an increase in difficulty from the Lower Citadel, with Fester and Rottie being two very different, but equally challenging fights. TDC decided we'd focus on Rotface first. This proved to be a somewhat painful decision...
The Rotface encounter is all about control; control of adds, control of movement, control of timing and raid movement. At its most simple, the encounter is easy. Avoid the bad stuff, move your add to the add tank, and maintain steady role performance in light of these requirements. In actuality, this encounter caused TDC a lot of broken eardrums from Ventrilo "encouragement" and "correction".
The real trick with Rotface is ensuring that whenever a raid member spawns an ooze, that ooze must be moved expeditiously to the add tank and combined with the big ooze he/she is kiting. Once a total of 5 oozes have been combined in this way, the big ooze explodes, and the process starts all over again. As the encounter progresses, the adds spawn more frequently, and the pace of kiting/exploding/avoiding the bad stuff gets more and more frenetic. During the majority of our attempts, we consistenly hit 25% before the chaos overtook the raid, causing wipes. After working on this encounter far too long, we focused on getting the raid to stay calm, look for their kite path before the add spawned on them, and move quickly once it did. This controlled approach led to our eventual victory over the smelly mass known as Rotface, and set up the opportunity to end Professor Putricide's lovely little nuclear family.
