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

Honestly, I'm cool with CS for healers. It raises the skill ceiling and differentiates the good from the bad (or lazy/learning) healers.

If I could change anything, I would make it to where tanks have a similar skill that swaps VIT with STR that works identical to CS, and have everything scale of STR still.

It would turn Tanks into DPS when they weren't tanking. Of course, it would make it completely impossible for them to tank at all while in it, so they'd have to take it off to MT or pick up adds or whatever. But, basically a healer becomes worthless as a healer in CS so I don't see why giving tanks a similar mechanic would be undoable. In fights where only one tank is necessary it would be golden. It would be a little cumbersome to use because tanks are also dealing with offensive/defensive stances, but, like CS, it would just raise the skill ceiling significantly.

ETA: However, I'm confident that the devs have thought of this and decided against it for whatever reason. So it's basically just a musing of mine - don't expect it to happen.
