Obviously there are exceptions, but first you all pushed a lot of the decent tanks out of Duty Finder.

"You're going too fast, stop or I won't heal you"
"Pull more, wtf y r u so slow"
"Wtf tank hold aggro" (died to untankable add or random target mechanic)
"Wtf tank, position the boss right" (failed to avoid first boss in Qitana Ravel)
(Charges ahead with Sprint pulling mobs - tank is expected to grab, aggro and tank them all regardless of cd's being up)
(Dps die 6 times over the dungeon. Tank dies once on last boss. "Wtf tank sucks!" Dps kick the tank.

Second, tanking has devolved into an extremely dull basic dps rotation that does no real damage. Emnity doesn't really exist and you only need cd's occasionally at set intervals. It's boring to tank, there's little to master and not much depth to it.

So all you're left with who has any interest in the class are players who like super easy because they aren't too good at the game, and that arrogant guy who thinks he's gods gift to PF, does everything wrong and is immune to criticism. Enjoy.
