If tank damage is now based on VIT, why do healers still have Cleric Stance?

[UBERHAXED]

Vit doesnt increase mitigation only health pool, there are no attacks in the game that require full vit HP so a tank without any str acc is wasting potential dps. Unless you have a terrible healer, full vit is pointless.

You'll find most raiding tanks will have at least a few str acc and will swap stances when necesary. Its the optimal way to play.

Oh there are. Tanks just use moves which prevent them from dying to... prevent them from dying. If these skills didn't exist (e.g. Holmgang still had the same effect as 2.0 Holmgang) you can bet people will be wearing VIT to survive attacks.
