The game needs to get the 80-90% DPS and 10-20% Healing down to like 40-60% of either first before considering making either half more interesting, personally i prefer 70%+ healing and a lot of effort maintaining my resources, but I don't see it happening but at least balancing out the amount of time you have to do either is a more worthwhile endeavor.

And why they hell are people playing healer if they want more interesting DPS rotations... There's 3 times as many options for that out now/soon, pick one, any one. Same with tanks but more twice as many than thrice.
