I would really rather not see "zero sum" talents - the "+5 to this, -5 to that" sort. At best they're "Why bother?" and at worst they're an exercise in gaming the system.
I'd actually favor having fewer, bigger talents where you don't take one very often, but when you do, it's a big deal in terms of its impact on the character. It's difficult to avoid math-based talents in a computer game environment, but something like the "Throw Enemy" suggestion is a good start, but I'd be inclined to expand on it so that taking the talent means that throwing stuff around - in combat or otherwise - is a defining element of the character.
