Well, this certainly is an interesting topic.
Personally, I remember strats for Bismark EX that had healers responsible for one of the tanks during the sanuwa add phase. As an AST (in diurnal) I used to loath watching WARs and would avoid them if I had the option; their HP just tanked so much more rapidly than PLDs (and depending on how good they were, DRKs). It always seemed better to have SCHs focusing on them. Then again, this was before AST got their meaningful buff and felt like a handicapped healer to begin with, but WARs always felt like the tank I struggled the most on AST in diurnal to keep alive. Don't really notice it so much now.
