Changing assist to "takedown"

Takedown is already a game term, though, for when you contribute to killing a specified target, be it by kill or assist. As an example, Devourer gains stacks from large monster takedowns rather than kills, so you still get the stacks if you weaken a buff and donate it.

Besides, it sounds too close to kill to get the point across. It's called an assist because you assisted in getting a kill.

it is still technically a takedown though

Nah. Go play that crap game by Blizzard if you're into that kind of thing...
