Is not dps'ing that rare?

[Lazka]

The main argument is - why should the DPS and Tanks be expected to participate in 90-100% of the dungeon and perform reasonably well when healers (who have many, powerful DPS skills mind you) participate in 5-10% of the same dungeon and recieve the same rewards?

uh oh.. so im keeping the party alive is just a 5-10% worth for u guys? and when im DPSin im at 90-100% performance healer?
this logic fail me...

then why u need a healer in 1st place then?
