Assassinations would be awesome some hand to hand animations for when you strike an opponent in the back. Although, it would kinda s*** at the same time if you can still be shot while in the animations and annoying if you were given invulnerability frames. So, maybe a strike and hold to initiate an assassination while a quick press and release would be a basic attack. That way it is up to the player if they want to stick around for the assassination or do a quick jab and dash.
