Hmm...I don't recall one for bash' date=' just one for Mace w/ a name similar to such. However, I don't think +% to it is all it would entail, but perhaps a chance to push through Prot. Shield (1% chance or something nil, but random enough to be cool).[/quote']
shakes head There's no point in doing that. If I'm fighting a cleric who's got prot shield up as a warrior, it's pure idiocy to bash even if I have a 10% chance for it to go through, because those three rounds I'm lagged the 90% of other times will get me killed. If you're going to suggest an improvement to bash, it should actually improve it and make it worthwhile to use in situations it wasn't before, not just help idiots who don't know to do more than spam bash during every fight.
EDIT: To be slightly more constructive, perhaps make it so that those who take bash mastery have bash ALWAYS go through prot shield, but have only, say, half or a third of the lag of the normal bash. Not really advocating this, but IMO it'd be a better change.
