I see where you're coming from. But is it actually possible to have something that benefits the weaker gamer that stronger players can't benefit from?
I completely see your point, but don't feel it will be an issue. Assault will almost certainly appeal more to KD fanatics.
I have a 2+ KD & WL in the all the COD games I think. I'm an objective player. So this will appeal to me as I like to help the team. I also like blowing the crap out of people while I'm doing it.
the thignis that even if the goo for the highpoint streaks thy might only be able to use once or twice in a game so they wont really be healpingn their team very much, personanly i would go with 5 balistic vests, 8 sam turret (get those pesty helicopters out of the way) , and then 18 protected air drop, i probably wont be running the last one very often becaue i enjoy helping my team win/counter against my enemy
