A bit late but I'm at a point where I agree this would be a good idea. Tanking and Healing became so much of a no-brainer that I'm constantly bored no matter what class I play.
I'm still salty how boring they made Astro with the big changes and I will never not be salty until they change it back, lol.

Sadly, seeing as the game becomes more and more casual friendly, it'll probably only get worse from here.
