If anything, I feel they could be more flexible about balancing the support we already have on offer. Not in terms of raid balance (though obviously that has to be considered with any changes), but just in terms of fun. I feel that my BRD and even BLM offer more interesting support than my WHM, outside of the obvious healing duties. I want to help people more, and in more interesting ways, but I don't think we need to rework the core party design to accomplish that.
