Why is it that proper tanking isn't a reward enough?

I've seen tanks wipe raids in LakEx and SusyEx because they failed at mechanics. They failed to tank swap or perhaps turned a cleave on the raid. It seems most tanks on this forum don't attribute this activity as helping, when they should. A Tank's (major) contribution is the flawless execution of the bosses mechanics and damage as to save the raid from being one shot by the boss and maximize the raid's damage against the boss.

Yes, we definitely need to do SOME damage, but the 100% focus on dps is truly infuriating to me. We can't ALL be big member DPS. This game is a holy trinity MMO. We, the tanks, are there to soak damage, position mobs/bosses, ensure the raid or group stays safe, and throw in some damage.

The problem is, and has been, an attitude problem with the PLAYERS. The changes to accessories is an attempt to force a change in that attitude. Either change your thoughts, or change your class.

Your choice.
