I actually don't find perks or killstreaks annoying in MW2 at all.
It's annoying when one player feeds another so he can get a nuke, but apart from that, I always go hugely positive even if I'm just running around. Even commando pro doesn't annoy me, if you can see the guy on time, a shotty usually does the trick.
This looks similiar to MW2 but with a bunch of quirky additions.
