Killstreaks kills shouldn't count towards getting a killstreak like in Black Ops. Adding new and different killstreaks would be nice, but I have no idea on what would be good. I just have improvements on the current killstreaks.
3 kills = UAV/Recon/Spyplane
3 kills = Counter UAV/Counter Spyplane
*So you have one or the other. You either spot the enemy or counter their radar*
4 kills = Care Package
*Only give killstreaks 3-7, also should drop the Sentry Gun as a random like the Death Machine, as having Sentry Gun as just another package drop killstreak is a waste of a slot*
5 kills = Predator Missile
5 kills = Precision Airstrike/Napalm Strike
7 kills = Mortar Strike
*Is kind of like a better Predator or you could think of it like 3 strikes like in Black Ops*
8 kills = Harrier Strike
8 kills = Attack Helicopter
*The Attack Helicopter should be like the Black Ops version, requiring 2 missiles to take out, so it equals the Harrier in some way. As the Harrier has an airstrike the helicopter should be harder to take out but not too hard*
9 kills = Stealth Bomber/Rolling Thunder
9 kills = Emergency Airdrop
*Airdrop only gives killstreaks 3-11, obviously killstreaks 7-9 are more common in the Emergency Airdrop as it is a 9 killstreak*
11 kills = AC-130
11 kills = Chopper Gunner
*AC-130 should have the same time on the battle ground as the chopper, it was ridiculous on how long the chopper had to stay on the battlefield. The MW2 Chopper Gunner was horrible, the Black Ops 9 killstreak Chopper Gunner was quite balanced*
15 kills = EMP
*It actually cancels the nuke or delays it when the nuke timer is on, instead of just delaying killstreaks before activation. It should have a better purpose of actually freezing the timer temporary on the nuke*
25 kills = Nuke
*I know it's removed. But it would have been better to have that without killstreaks helping you get it, as it shows you actually deserved getting it*
Boosters in public matches should obviously get reported, boosters who boost with a full party and lock a lobby for themselves are no concern to me, I really don't care. But it makes no sense when you think about the game as being a game, and the actual competition of the game is solely based on shooting and killing and not rank, so having the Cage Match game mode wouldn't really hurt anyone. And if you think about boosting to get rare titles and such, they should just disable challenges in Cage Match. It should just be a raw 1v1 gun match with no experience from challenges but only from kills. Having a High K/D or W/L doesn't really matter either, all you can do is boast but you might lose against someone with a low K/D. And the W/L is a stupid stat addition when you join half-way games and end up losing you get a Loss, but if you win you don't get the Win?! And lock search & destroy lobbies that are at 3-3, it's really annoying to join those games and your team loses and you end up with the loss on your record, and if you win you don't get the win as I mentioned before. And a nice addition might be to have an option like Change Class, called Change Killstreak, works the same way as change class. So you would be able to select your killstreaks for certain maps/gametypes that you get put into half-way instead of having to suffice with the streaks you have set already.
