The whole idea of a more elegant tank is kinda growing on me, using RDM as a base what if they did it like this...

Weapon instead of a regular rapier how about a dual aspect weapon similar to NiN and MNK with one side being the sword, the other a small buckler similar to Scottish weaponry.

And what if the stance switching could be done as the En-elemental style?

Ex- tank stance could be Enfire giving a passive boost to enmity and defence and a penalty to dmg and adding cast times to certain skills.

Ex dps stance could be En-thunder unlocking certain AoE skills and increasing base dmg by 20%

Ex tank oh s**t button En-Aqua adds buff fluidity for 15 sec increasing parry rate. Unlocks skill (let\\'s call it elegance) where the next 2 physical hits are dodged with a penalty afterwards.

Finally giving an ability that let\\'s you switch your Auto attacks from doing physical dmg to doing magical damage giving credence to the whole Spell blade theme
