Stolen Kills/Xp?

[Iceman]

Very Often, it happens that in a firefight, i will shoot at an enemy, but the guy next to me 'finish him off' and gets the kill and Xp.

The XPpoints system doesn't seem to 'distribute' XP amongs the users. What i mean is, if i inflict damage on a target, i should get Xp for it... even tho i didn't kill 'it'.

I was wondering if the Xp system could work close to the grief point system. While every damage point inflicted gives you and equal amount of Grief points. That could be a very good way to calculate XP on a 'damage/kill' basis... it would basically be an 'assist' system.

Any thoughts on that?
