Love this game. Love the multiplayer. Love that they are trying to make it better to save profiles between upgrades. I think this is important to the players, like me, who have owned every COD. It is a game of milestones but, how much can be stored, I get it.
Call of Duty is the best. My first game console was Telestar( tv tennis). If you never heard of it, I've been doing this longer than you.
Don't turn this game into dungeons and dragons. Load up the teams , choose your weapons, go at it. This is what works with online play.
