Actually, you completely missed the point of my example. I made the abilities powerful to make my point, it doesn't matter how powerful they are as long as they are all desirable. The point I was trying to make was that you shouldn't be able to take whatever you want. Not because it's "overpowered", but because it creates an environment where there are only cookie cutter builds, at least in terms of enhancements. My point is that you should have to make relevant choices.
I made the 3 abilities overpowered to help emphasize wanting all 3 abilities.
