My two cents are pretty simple. Having played mainly as a red-line mini, I am not too unhappy with that end of game play. Sure, we can't DPS like a hunter, but we can heal.
And that is where the problem lies. In order for us to be able to heal Abyss T2 and other stupid hard content, we need the massive heals. For anything else, it is massive overkill. But that problem lies more in how hard some of the content is. Abyss T2 is too hard. It is silly. I've tried it a few times, never going to try it again. I simply don't feel like wasting 5 hours only to die 13 times and only make it to the 1st boss. I'd rather work on an alt.
And now that my healing has been nerfed, I have even less reason to try the endest of end game content. If my healing gets nerfed, why not try to bring the difficulty level down a touch? I find that with many instances, the jump from T1 to T2 is crazy high. I feel like I went from T1 to T10 half the time. Maybe there should be 3 tiers: one for easy, one for hard and one for insane mode.
It wasn't that minis were stacked too high with heals, it was that we needed too much for only one single raid. Don't just balance us toons, maybe have a think about balancing some of the game play.
P.S. I am so pleased that we get visible instruments! I put that on the wish list year
And I apologize in advance to all of you for returning to the bagpipes.
