My statement wasn't exclusive to raids. By "raid healing" I am referring to AE healing/getting multiple people healed up quickly. The other points I made didn't even have anything to do with endgame at all. So I didn't "avoid" anything. That's their identity. If you don't like that identity, level another class. It's really as simple as that. Whm is the same it was in ARR as it is now, save the loss to protect (which was a must change anyway), and stoneskin (which I personally don't think was necessary to change). So if you liked it then, there is no reason to not like it now. If you don't like it now, then it's not the class for you.

I played whm a lot in ARR and prefered it's playstyle over sch's by a lot. It's role in groups and its identity in general are exactly the same now as it was then, save two minor changes and 5 new tools to help do what we did before even better.
To go further into this .. I'd also say that WHM is the most "simple" (and I don't mean easy, just less complicated, mainly) healer compared to SCH/AST. A lot of people seem to enjoy that aspect, since there's not an extra resource, pet, or cards to manage. It's still the king of burst healing, which is what it was in ARR; nothing about WHM's identity has changed with the addition of AST or SCH's new skills. If you like the new toys that AST/SCH got, play them instead; nothing is stopping you. None of the healing classes are "better" but each fill a slightly different role with slightly different play styles, which is completely fine.
