The guy who gets kill should have the kill points, even if he stole it. However it does irritate people to get 25 points as if they had put two rounds in the target whereas they blew up 90% of the enemy health.
CCP should implement progressive rewards, 12 points if you helped a bit, 25 if you did between 40 and 75% of the damage, and 40 points if you did more than 75% of the damage.

In Mass Effect multiplayer, it gives you a percentage of the points depending on how much damage you did, regardless of whoever killed the enemy. For example, if I destroy 75% of an enemy's HP and a friendly kills the enemy, he will earn 25% of the 50 WP for the kill and I will earn 75% of the 50 WP for assisting.

This idea has been discussed at great lengths in another thread. Mostly we have community support for the BF4 style of Kill/Assist scoring. Do a search and check it out.

Pretty much that Blaziken. Although, if you do over 70% of the damage in BF (and someone else takes your kill) you both get a kill on your record. I'm not saying we need to go that far...for me the assist WPs being related to actual assist damage is enough.

Before this though, Assists in end of battle screen and ADR in character record please....that's EASY to implement and people would appreciate it.
