But killstreaks encourage more kill****** in Objective Game Modes. Scorestreaks reward you for actually helping your team which is better IMO.
95% of the games i play are TDM 4,5% are KC 0.5% ar misc. playlists
... i couldn't care less for what people do in objective modes. I do like the killstreak system in my preferred modes
Tbh the only game i liked playing objectives was the Rainbow 6 Vegas series, but those games play entirely different to CoD, so objectives are more enjoyable imo. --- Hey i'm not camping ... i'm "tactically waiting" :-D
