2 words... a finisher.
Most of the rest i completely agree with but it would be nice to get a "below 30%" finishing move like other melee classes have.
I thought about this also but we would be way too strong with it. As it is currently on live, if I catch someone with stun break on cd and no force barrier, they cannot even attack me until I'd be ready to use assassinate/vicious throw/etc a solid 75% of the time. This is even true for tanks, but maybe only 50% of the time, requires crits. If we could do that still, and in fact better, and
have an execute? Broken, nerf nerf nerf nerf nerf.
