Removing Tank Stance Argument

[Kabooa]

Tank Stance: Decreased damage taken/increased healing and Max HP.
Offtank stance: Decreased threat generated.

No damage penalties, no damage buffs, doesn't screw up current dungeons or raid mechanics, and it doesn't mean a massive gear difference between tanks will cause one tank to monopolise threat even when they really don't want to (although maybe I'm just talking from raising an alt and not being able to hold threat against people scaled down for trials)

So only ever use Tank stance, because Shirk exists.
