Yeah, and if you're warchanter people really don't care about the build beyond that. If you're spellsinger like I was playing and you're aiming at doing CC then you have thresholds you have to meet to do your job. If you're a melee Warchanter you simply do the most damage you can possibly do while adding damage to the group. The most stressful thing I have to do now is plan my madstone rages to make sure I can still rage/haste the group. If I can luck into an arcane willing to do it then the most stressful thing I need to do is remember to sing and pay attention enough to cancel my madstone if things go badly.
I was raid healing on the Spellsinger version and while it's fun that's a lot of work for a pretty much thankless job. I carried quite a few PuG clerics through Shrouds only to have the raid say, "WOW! Great job solo healing <<useless_PuG_cleric_42>>". Now I just hit things with my big (wish it was a falchion instead) axe while whistling a tune.
