I actually tend to think MA is worthless for just about all of ToC. PC will kill you every time unless you get a full resist (which is pretty unlikely even with MA, but it can happen) or a heal before the first tick (second if you don't suck and hit frost ward / stone / frost pot). The damage reduction will reduce your healing done to anub from swarm due to nature resist, but that's fairly minimal unless you have PC for a large part of the phase.Originally Posted by thegempolice
I still run with MA in my arcane spec, but there isn't really any random "lolgibb" magic damage to speak of in toc when compared to something like thorim/mimi/freya.
