I had an idea for a new class for the Samurai faction. The Monk.
the Monk would have no heavy attacks, instead, they would have a high mobility 'stance' when they hold down guard, and the primary attack would be a punch, and alternative to heavy would be a kick. the execution would be given to them, if they deal the final blow to an enemy like a normal heavy attack. The alternative would be a Bo staff with moderate damage and high stun
I can't figure out how to edit my original post, so here's an addendum.
The monk class would be a true harasser class. Doing minor damage at most, and focusing on grabs and fast low damage punches, with moderate damage kicks thrown in for combo's. The bo staff would focus on putting your opponent off guard, and off balance while doing low to moderate damage as well.
