HOT TAKE HERE:
Tanks should not have heals except 1 on a long CD (yes i dislike WAR design). You are tanking. Mid and shields is our job not outheal a healer.
W2W should not be the norm and require skill. You are a casual and not skilled enough = NO W2W. I think W2W is a bane of this game.

Stop giving "win buttons". Easy to learn, hard to master. A full xpac with nothing to learn and be bored out our minds is enough. The skill ceiling we have now is how much boredom can i bear before I fall asleep.
