For every game, my go to class is healer/support. Always has been. And since ShadowBringers I rarely play healer on FF14 anymore. The class has become stale. These Dawntrail changes just solidify the death of healer for me.
Unless they make some drastic changes, I don't see healers coming out of this alive.
Expect longer queue times, and the eventual death of the game as it will become a healer less mmo.
