I disagree on Heartless Angel. It's too hard to hit with it, it should stay.
Which brings me to my original point. Since it's so difficult to use why can't we make it like the actual attack and remove all the knock back and up the damage to 40 to balance it out?
It wouldn't be broken because it works like once every hundred times due to being so impractical. And spamming it would only make it even harder to use because of it's incredibly long start up.
I don't see what the difference is between tons of damage or tons of knock back... at least this way it will work the way it's supposed to.
