Merle, I feel your pain.

By the way ...

The Howling Eye (Extreme) / The Navel (Extreme) / The Bowl of Embers (Extreme) / The Whorl Eater (Extreme) / Thornmarch (Extreme) / The Binding Coil of Bahamut (excluding Turn 3) / The Second Coil of Bahamut

I don't think I know somebody who has fought in 200 of this duties.
Are they really trying to Thank "seasoned" tanks or to troll them?

It does say "As of 2.2", so maybe it will retroactively count earlier stuff for tanks who've been doing all the 8-mans before 2.2.

Edit: So wait, I guess mount collectors will just be grinding myth tomes on their DPS, i90ing their tank, and grinding turns 1 and 2?
