Personally, I miss all the old support tools we used to have; Virus, Disable, Eye for an Eye, the Slow of Shadowflare, the Knockback of Fluid Aura, AST's old cards.
There was a lot of potential in evolving healers to provide unique buffs from one another but they instead decided to just give them the same basic toolkit with a different shade of color from one another and call it a day.

Since they decided to leave only purely mitigation tools for healers and lowered their DPS rotation to a single button, Healers have become needlessly dull. I just want more to do
