The only time I get ticked as a WHM in Brayflox is when a tank shows up as a class (MAR/GLD) with lv25 grey gear or lower. They don't tank any better than me at that point with paper armor. Typically they pull, get hate, down to 1/3 life after the first round of hits, I cure, boom I'm tank for rest of the fight. Needless to say bosses go nowhere. When I get tanks like that I kindly ask them to go get their Job counterpart at least, which gives them at the very least more HP, and I swear a hell of an easier time holding hate (internal enmity+?)
