Samurai as a tank but let me elaborate a bit on what I mean. I'm an avid fan of the way it was done in Final Fantasy Tactics. Draw was the main skill in that each katana would perform different abilities when used. The drawback was that they were like usable items insomuch as when they broke after a draw you moved to the next one in your inventory. What I propose is this: Use draw skills much like combos where say a thrust>downward slash>crosscut gives a skill at the end of a chain then if you do it say crosscut>thrust>downward slash gives you another skill to use at the end of the chain. Also give them two stances one for tanking the other for dps that way those still learning the skills wont accidentally grab agro while in a boss fight. Skills could heal, do crit damage, dots, damage mit based on stance currently in. As far as heals go, no idea.
