I'm torn. On one hand, I like plowing through enemies with minimal risk when I want to. But to be honest, the way the system worked really changed how I played the game, to the point where I didn't play it like a Fire Emblem game (yeah, I know I didn't have to use it, bbut still... I have OCD about being OP).
...so I also wouldn't mind a rich, balanced game like the olden days.
I don't think the idea is inherently bad. Natural Doctrine managed to do something similar (similar to Dual Strike anyway), and that game is no slouch in the strategy department.
