It comes back to the point you made in the other thread Moz about the synergy in Holy being too complicated. I want to cast Flash Heal because I want 2 stacks of Serendipity. No, wait, I want to cast the spell that will keep my Chakra state up. No, wait, I want to cast PoH before my 2 stacks of Serendipity expire. No, wait, I want to cast Holy Word:Chastise, but I actually want it to be Chastise, so I need to let the Chakra state expire. No, wait...
My Holy wish list right now:
1.) Get rid of Serendipity entirely, or change it to suit this new stance-style healing.
2.) Simplify going in and out of chakra states. Chakra is cool as hell but what I've done mainly since the patch is battlegrounds and in that environment I can't use it to full advantage with the current mechanic. I want to be able to change states the way a druid can change forms. (Yeah, okay, why don't I just ask for a million dollars and unlimited pie, but you know, it's a wish list.)
3.) Fix HW:C in some way that will let me macro it to one button. Holy Word is awesome, and I love it, but it's kind of hard for me to use. I've tried speccing both with and without Revelations and I have to say, right now I like without better. But I feel too guilty that way, like I've somehow wimped out on really learning how to play Holy.
But I admit a lot of this is learning curve on my part rather than something Blizz should actually fix. Serendipity, though, does need their attention.
