Problem is:
-IF you clear a fight: "wow gz!!! That Dps tho ! amazing" "omg look at my parse!" "Holy--- that 5k DPs OMFG" "LOL you're Tank dmg is almost like a dps that 3.5k on tank omg"
-If you do not clear the fight: "What? why? ... oh my hp wasnt full" "WHY DID YOU LET ME DIE?" "im dead, i was 25% hp and i didnt get a single heal :C" "Focus on hp please"
When people celebrate a fight, do they check at healing parses? nope, not even healers does.... They look at dps parses, and who are always at the bottom of the list? yep, healers, they arent part of the fun AFTER you clear something, tho they are the causes of the wipes BEFORE you clear something..... i know healers are not dps, but neither are tanks and they can still push 1.5k/2k more dps than a healer, yeah yeah tanks keep attacking all the time while healers need to stop attacking in order to heal, but guess what? even if you go full dps on a healer, leaving your co healer doing all the job, you still wont be anywhere close to the tank..... Tanks have fun optimizing their dps and their up times droping tank stance and such, healers cant optimize anything but keeping dots up and just spaming 1 spell till healing is needed....
Im a main healer, if you ask me what would make MY job more fun, it would be something like a burst window when i dish out tons of dps (similar to WAR's FC set-up), and in order to open that burst window i would need an special no-mp resource that i gain from attacking and/or healing (healing would give more of that resourse than attacking)... no, i dont want stance dancing back, if a tank mess up their stance dance they'll just take more dmg than they should, hence healers adjust, or they die, hence OT take agra asap and healers adjust, before with healers stance dance, if the healer messed up the dance, the tank died, the dps died and the party wiped, so i want a burst mode that doesnt stop me from doing my main job, but that also let me have fun watching at my numbers (yes, belive it or not, numbers are part of what makes dps and tank fun).
