well dont juge me hard i have just some ideas abaout disc and holy spec ... i realy dont care abaout shadow:
Change Surge of light and Grace places. Disc benefits from crits more than holy and we are main tank healers as disc so instant flash is awsome. and Holy could use grace becouse they dont have such type talent and that would help them a lot while aoe healing wouldnt that !(should be able to use with CoH and any other healing spell.
Second- rapture should affect Penance damage as well.
Third: Reflective Shield should affect Divine Agis too..
Well thats some of my ideas DOnt flame me for spelling becouse i have forgote how to write the real names of the spells
