Toxic DPS

[Absimiliard]

"DPS dictate the pace."

Tell that to all the DPS that start whining if the tank is going too fast. No self-respecting tank is going to slow down because of this.

That aside, the tank jobs have strong enough AoE that half the time they probably don't even need help from the DPS, and two of them don't need a healer anymore. Speaking purely in terms of dungeons, of course.

Every role in a dungeon is of equal importance. Without healers the DPS will bite it, without DPS the run will take needlessly long, and without a tank ... well, honestly, you can do most dungeons without a tank if you have a very tolerant healer and use feint on tankbusters. By that same token having a WAR or PLD tank eliminates the need for a healer for the most part, and any run can be done without DPS if you really want to.

Tl;dr: everyone is equally replaceable, and attempting to downplay the importance of one role to prop another one up is a bit silly.
