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

[CorbinDallas]

Manipulator and Living Liquid both auto for as much as Bahamut does. There's a reason people are sitting out of tank stance 99% of those fights. If you think that player skill has gone up so high that we've reached the point where despite damage being exceptionally high (apparently) we can spend near entire Savage fights out of tank stance in near full STR accessories... I don't know what to tell you.

Funny, because Liquid crits like a mofo on his autoattacks
