Suggestion for the Assist Timer

For now, it can run out as long as a decent amount of time passes between when you last attacked an enemy and when your ally finishes them off.

I suggest that, instead, it only run out if the enemy wasn't attacked for a period of time by anyone, before your ally got around to finishing the kill.

For example: Now, if 10 seconds pass between your auto on an enemy and the jungler killing them, you don't get the assist. My suggestion is that as long as there wasn't 10 seconds between when you attacked and when the ally started attacking, that you get the assist even if you leave.
