I am sorry, but I just can't agree with this.
I understand it is just to help or be nice to other people but this would also generate various problems, such as people threatning others for not giving them points and stuff like that.
In general I just can't really see the use in this that much, like, I guess it would be neat for some but not for all. Also, if they leave the server then the points might be wasted, but not the great time they had on the server which is what counts, the points are just an extra kind of reward that you use to get kits but other than that It's worthless and just there as a decoration. I hope that makes sense, if not then I am just saying that points are worthless and that this is not really necessary.
Anyways, keep suggesting!
