Well, first off I think that you shouldn't have started anything about him being foreign. You can easily tell that he's trying his best to type english, It is hard if you don't know the language...
Anyway, I think that you probably shouldn't be getting Assist points for your team-mates kills while the UAV is in duration, but maybe getting 500 Points for calling in the UAV instead of 100? I mean, 500 points can be equal to 5 kills, which is a fair amount of points. Also, you do have a choice of if you want to have your Killstreak as a UAV or something else, If you don't like that it helps your team, and you being a team-player than take it off, and Use a different Killstreak. But keep in mind, that when you use a UAV, it also helps you get a lot of kills too, so it is a pretty good deal considering that it is only a 3 Kill streak reward, and 2 if you are using Hardline. So, just a couple of things to consider when you are using the UAV.
