I don't think those would be any real fixes with keeping balance on, because they would have to double shockwave and heroic leap damage for them to be "viable" again, if you look at it with PvE side... and bang, that already gives more burst issues again, doesn't it? Although they could just reduce bladestorm cd to make it more useful (1min?), or increase that damage a bit so people would consider other choices than just shockwave on PvP.
