-So no more stance dancing, they effectively removed stances. Yes, technically we have a "tank stance" but it's more of an enmity toggle than a stance.

-Design was so that all tanks can equally MT or OT depending on choice.

-More parity between tanks while avoiding too much homogenization.

-Fixing the stat problem (vit/str meld issues)

That's what I can think of off the top of my head. Anything else you noticed? What do you think of their changes?
