i agree. imo cod4's mp, the fact that WAW was in WWII (the most recent one at least, im hoping they get back to WWII with a more advanced gameplay adding good elements of the games that have past), mw2's guns and some maps, bo's proper balancing (except for certain FAMAS things, i know know)and spawn system and finally mw3's specialist package and unlock system (with the gold guns proficiencies etc.)
