Oh, definitely. I just like the idea of having everything they took away given back is all. Merciful Eyes would've been fine if it healed a decent amount, but as it was, it was pathetic. Maybe if it was about the same as Second Wind, at least, that would make it have something to do. But I agree that Senei/Guren, as they currently exist, should just be procs over Shinten/Kyuten through Ikishoten.

So many has already been said on those ideas, though, so I won't reiterate all of that.

The only iffy thing to make a solution for would be Shoha and Shoha 2. It could just as easily be a targeted aoe with falloff as so many other skills already are. But there's also the potential for Meditation to be expanded on, thus it could either have it's own dedicated evolving button like iaijutsu, or it could just as easily change Shinten/Kyuten as a base for our redundant skills of single target vs aoe.
