I hope they're moving to a killstreak system like MW3. I have to say I really like having the option of Support or Assault killstreaks. It was a great addition to the series.
And keep the system that gave you credit for things other than kills such as capturing an objective in Domination and such. Nice that they finally threw some of us suckier players a bone so we could enjoy the better killstreaks every once in a blue moon.
I can't stand support kill streaks, especially the lethal ones like the stealth bomber and air drop. Recon drone drives me nuts as well. They are an abortion, imo.I would actually prefer they discard killstreaks completely over putting back in support killstreaks or deathstreaks. Personally, I don't get much satisfaction out of putting up KS's. It's the rush I get from, say, killing 5 guys in under 10 seconds, that keeps me playing this game (and its also the main reason why I don't like BF3 outside of the close quarters maps). Come to think of it, I think the best COD would be where they get rid of all streaks except Specialist, and up the difficultly level for acheiving the Specialist bonus.
