Improvements need to be made

What improvements would you like to see in the upcoming Modern Warfare 2?
I would like them to improve on...

Timing of bullets so they match up

More variety of perks

When you start to prestige there should be more challanges for you to complete
[Different Ones]

Make the helicopters less accurate

X3 grenades needs to only be X2 [like in World At War]

So what would you like to see in modern warfare 2?

After seeing the perks and killstreaks awards it's just unfair for a player with less FPS experience. Sure there are deathstreaks etc. but seriously i'd rather have an AC-130 over martydom etc.

Matches should be based on rank.e.g 1-10, 10-20.

I'd like to see an unranked feature so you can play just for fun, and wont get raged as hard for tking your whole team in hardcore

I'd also like to see the best weapons unlocked earlier so those who play longer wont get a ridiculous advantage. In Cod4 this worked well since i would consider some of the best guns the default ones e.g Ak47, M16, M40A3

catseye has some great ideas. They are all good. I also would like to see less accuracy in all the guns. I mean, you should NOT be able to snipe someone across the map with a Deagle. (although, it's funny when you nail a sniper in last stand!
