With the removal of commando, one man army, and half of scavenger (only ammo and grenades get picked up), Treyarch is promoting clean and fair gameplay. Now I know it's fair to use a noob tube (STFU IT IS) but not fair when you have unlimited ammo for it just blasting away at there spawn. I know it's fair to knife people, but not when their 20 feet away from you. Treyarch is looking (IMO) at every aspect and trying to make their multiplayer the best of any game so far. It started from day 1. So before you start bitching and moaning about, "It's just going to be a MW2 clone why should I buy it?" you should really understand Treyarch and that they "care" about their customers. Their not going to give you a half-assed product like Infinity Ward.
Now about non-chaining killstreaks. This DOESN'T promote camping. See if you really, REALLY,REALLY, think about it... How is someone going to get a high killstreak if they camp? It's not possible, because once someone gets killed by a camper (i know it's kind of stupid but we all know it), that camper is their priority, and he's going down. So, they very rarely (IMO again) ever get killstreaks, BUT their killstreaks already in the air get it for them. See it's like this, it's all about leveling up, showing you friends who's boss, getting all the gold guns first. Pretty much getting that highscore, and you can't do that with camping, but you COULD do that with camping in MW2 because the killstreaks played the game for you. So after a few games they will realize,"Damn nobody is coming to this area let me move over there. Woah! there's alot of people, cool killstreak! *camp**camp**camp* Damn, everybodies gone again, lets run over there. Oh sweet another killstreak. I think i'll start running around, I get more kills and it's alot more fun then just sitting in one spot." Now that their killstreaks don't play the game for them, there is ALOT less reason for them to camp.
NOW I know people will ALWAYS camp, but that's just their play style. Now with removal of OMA and scavenger, non-gameplaying killstreaks, they are more inclined to roam around and actually play the game, instead of sitting in the corner getting rare passerby kills.
