Youre all over the place, thats the problem. You say “priests have the best raw healing”, you dont qualify that as disc; your mixing reasoning about mythic raid with bg pvp; i dont mythic raid so i dont care. Your conflating hps with survivability in pvp; etc.
Im at a point where i simply dont care what you think, and theres no way im going back to disc in casual pvp on the basis of your arguments.
