Increase XP reward for assists depending on the amount of shots****ting the target. It's annoying having a teammate third-partying a kill and getting the XP you're trying to earn, especially if you hit (for example) 9 shots and they hit the last bullet to kill the enemy. While you who did most of the damage gets barely any XP, this person who came in at the last second who stole your kill gets all of it.
