DEDICATED SERVERS. ugh. With all the profit they make there's nothing aside from greed standing in between call of duty and dedi servers.

BIG Leave-Game PENALTY, especially when quitting from losing team. For all those rage quitters. This would also help with how I also get put into a match where my team is already down by 100 and the other teams has dogs and a chopper gunner already active. Doesnt need to be as strict as halo as to where nobody can join in-game, but seriously..
No OMA. scavenger is enough.
NO LAST STAND! this is worse than noob tubes!!! Why is it still in Black Ops?? I kill somebody, it's extremely annoying for them to be able to still kill me and several more people.
Cooler, more useful kill-streaks.
Like BO, no kill streaks should count towards the next. No more get a harrier then ride it out to get a nuke.
MORE customization. I.E. let us customize camos or give us more, cooler, funnier, awesomer ones. Don't just give us gold.. that's not enough and getting old.
More player customization! Don't base our appearance off of perks. I know it makes more sense, but i like being able to tell if somebody is sniping by whether or not they have a gillie, and etc. Please at least do not base looks completely off of perks. Also let us customize! let us customize gear, body features, body art, clothing, etc. i.e. Brink, Uncharted 3 and Socom FTB2.
Keep the customizable emblem, but give us earned unlocks within the emblem. dont just simply let us buy all of the components, but let us earn the emblems that can be used in our custom emblems. i.e. let challenges unlock our emblem stuff - and give us cooler emblem abilities.
Same with titles.. maybe even customizable titles / backgrounds?
The more customization the better! everybody loves it.
Keep out the XP lobbies and infections. Similar but even better than BO.
more even team balancing! look at past performance and leader boards. also on the second game, why are the people with the top scores put on the same team? Makes no sense. MORE EVEN TEAM BALANCING!
keep the player card!
Keep noobtubes like they are in BO.
MORE GAME TYPES! I am SO TIRED of all the same TDM and Demolition and etc.
Wager Matches are nice, but should also be available via normal matches!
i.e. a branch-off of the normal FFA mode; gungame, etc. where it's not only betting - but actual normal game modes.
And give us more of these different game modes! an official community branch of game modes? like in halo..
give us an official Michael Meyers gametype?
More wager match- styled gametypes - except within the normal multiplayer lobby - not wagering.
TDM and FFA with only certain equipment.. i.e. explosives only, knives and tomahawks only, pistols only, etc.
Powerful secondaries again! maybe not as powerful as in mw2, but atleast fairly powerful.
MORE BALANCING in guns and perks and etc.
MORE and MORE guns- but not just weak guns that nobody will use! Make them balanced - with their own unique attachments, pros and cons.
some stealth in campaign?
at least one fun stealth mission?
at least one fun sniping mission? Maybe sky-top sniping.. from skyscraper to skyscraper, etc..
PLAYER - MADE MAPS!? like far cry 2, maybe a public match lobby for official game modes on custom maps..
Maps that more specifically aim for snipers. Am no huge sniper myself, but feel that a sniping-only map or two would be tons of fun!
A smaller, inclosed map?
Cooler maps that feel awesome, like dark night-time office buildings and alleyways - taking advantage of gunfire-lighting effects and etc.
Just some ideas off the top of my head... :0
