you know what would make more sense in barebones?
how about no perks also.
It just seems kinda dumb on IW's part to strip away only the killstreak rewards and leave everything else in tact. Most people like to be "rewarded" for killing, and i doubt many people will play this mode. Perks definitely need to be removed also in order to make this game mode unique. Otherwise it's like playing a game where everyone sucks and is getting more or less a 1:1 ratio. In such a scenario, there would hardly be any killstreak rewards.
Either way, no killstreak rewards is lame to me, so I won't be playing it.
