I posted in one of the threads about some possible solutions, but it kind of got lost in the shuffle:
I am putting the finishing touches on a complex martial class that has seen years of playtesting, complete with its own power point system, over 80 abilities to choose from the "generalist" list, and currently a dozen subclasses, each with their own list of abilities to choose from in addition to the generalist list.
The class can focus on being a striker/ skirmisher, or a tank, or a support martial, but not all at once, with a limited number of ability slots.
Included are several non-combat abilities for added utility.
Players who have tried it say its a blast to play. My design goals are a bit different however than just "solving" any particular issue, and focusing on giving the class a range of tools to choose from to suit their preference in tactics and playstyle.
