Well. I've been playing a monk, and enjoy it. I just have a few things I wanna say about all of it.
First off, I like the ki for monks, but I don't really like the exact way it's being used and the enhancements.
I don't think you should get ki just to add lightning damage to your attack, to, if u get the right combo, use a finisher. I think that if you go a certain path, little bits of damage(1d3, 2d3, and 3d3...etc)should just be an added bonus to your attacks. And as you build ki, you should be able to use finishers, that you can pay enhancements for.
I beleive that would make for a huge improvement in monks.
