I think I understand and play my class pretty well, both Disc and Holy. So again, I disagree with you. Holy lacks a lot compared to Disc this raid, wether it be utility, output (both dmg + healing and as I said, take PW:B into calculations aswell) or raid encounters being designed in Discs favor.
I am very well aware what matters, and we used to have a very strong niche in strong raidhealing, but we lost the uniqness with all healers becoming smart raidhealers (often with more utility to).
We can agree about 1 thing, Holy do have issues.
