Gamplay difficulty should not come from having a hard time watching people debuffs, self buffs and being force to make additional mouse/keyboard clicks in order to keep people alive.
Yes, i am the healer. And while i enjoy healing much (it has a better model than WoW imho) lack of serious UI support for healers is annoying.
I need a buffs/debuffs monitor so i can see whenever if my buffs on people are up and if there is something to dispell.
Now it's terrible - i see small icons, some of them dispellable, some not, but i need literally to mouseover each time i need to check what the hell it is. While healing.
My buffs is also difficult to track - when my trauma probe fade off from tank, when my kolto residue fades off, kolto shield, hots and so on. Now it's nearly impossible on heavy damage fights so i waste my ammo to overwrite many of my buffs. That's BAD.
And healing. Lack of possibility to keybind actions on party/raid frames makes it really annoying to switch healing targets while using healing abilities.
