Well hiltslash was just another way for two handers to play, I never saw the problem with it, I'm not a great swordsman by any means and I would use it occasionally as well as be killed by it plenty but I never saw a problem with it, thing is with the way 2h feels right now I've been sticking with my polearm character, he feels far more effective in almost all situations. Given I'm a Ninja and I'm using a Katana I find it very difficult to get any non-backwhack kills. LHB I actually stand a chance in a 1v1 fight.
Might give the Miaodao a try, see how that feels.
