It's interesting how frequently that you respond with rebuttal such as "Solo content isn't tedious to a lot of people. There's zero reason all Healers NEED those. I think the problem here is that you think that all Healer players want what you do and feel the way you do. Many players find WHM, for example, fun and engaging"

You are backing up your opinion, and based upon likely empirical evidence and claiming it as fact- when you aren't providing any factual evidence (independently sourced metrics) to back it up.

Given that- it remains an argument of one person's preference versus another person's preference. You are "being a contrarian" , you have held to some positions- one for example being "It's explicitly WHY I think we should change SOME Healers but not ALL of them, so that both types of player have at least one they enjoy playing on. There's only one Healer in the game that has 1 DoT + 1 Nuke, and that's AST." - you are absolutely entitled to your opinion, however that isn't one that everyone holds.
