Maybe... The heroes and warlords could have some grab abilities that could execute a character almost instantly? I mean, those guys will be HUGE and really dangerous. Make them extra powerfull!
Agreed on the last point, sounds reasonable. Overall i think there should simply be more variety to the executions. And on a sidenote, not to sound like an ass or anything, but maybe...i dunno, a bit more character to those? Way i see it, most executions right now are kinda bland. They're not violent. Orks wave their choppas like they're sitting in a cubicle somewhere trying to hit their table quietly so their boss don't see it. Same goes for all the others, in most execution moves there's barely any real kick. Its good that DoW2 video was posted cus hell, executions in DoW2 and especially in DoW were full of character and violence, even with the graceful Eldar. And the Zerker executions, boy i could watch that shit over and over again.
