I understand your concerns, I think the rare actions problem could be remedied by having more predictable movement in the game and more precise items. Due to gravity and built-in physics, the game is very chaotic which probably makes the late game more luck than skill, unless of course you enjoy just watching a ball bounce around everywhere. I will keep this in mind if I pursue the idea by changing the mechanic in such a way to mitigate that problem.
Thanks for the insight!
