Example of UNFAIR: Your tank has been running raids for 9 months. He has gotten geared up, and he is a great player and tank. You have a dps who just hit level 90 that day and he beats the tank in dps all of the fights in that raid.
As a tank we don't - and haven't ever really complained or noticed something like that because our goal is just to tank. It's the whiny baby dps that notice our dps and call foul. This is very sad considering that we do put our time and effort doing dailies and gearing up, and we should be able to pull dps comparable to the gear that we have gotten and the time that we have put it.
