Many old school fans of the Call of Duty franchise would love to see clan wars come back in CoD: MW in a similar format as the one used in Ghosts. Clan wars gave us a furthar reason to spend weeks grinding with our friends. It rewarded us for grinding as a squad and playing at our best in public matches. It added a new level of competition and strategy. It encouraged us to try new, less popular game modes. Grinding for the next level gets old over the years, but clan wars would add deeper social interaction and a deeper sense of accomplishment to the game.
