Filling up seems odd.. and agree it should not be as it's the opener and we really don't have a good alternative.
I'm playing scrapper as well. When I get there, it will surely be annoying.
If the resolve doesn't get very high (not fillled, that is ridiculous), the opponent will surely die as we have blind, stun, root to follow, not to mention just dissapear if things don't go as planned.
I think stun should be the one to get the bar up near full, not the first knock down, or blind/root/knock down.
