There are no clan wars for Ghosts. Only Advanced Warfare has clan wars at the moment.
Ok can you please help me with this. i joined a clan with 7 other people in it. we did clan wars, and multiplayer game modes. we are ALL in the clan for sure i checked in the barracks. but we have earned a SINGLE amount of CXP!!!!! why arnt we earning our xp, i know were doing all the things that you posted... none of us have the cod app, could that be a factor? if you could PLZZZZZZZZZZZZZZZZZZZZZ RESPOND! it would be a great help for us!
FYI - For Ghosts I'm not sure if you can earn Clan XP still. The app no longer works and thus it is possible that much of that stuff is no longer working. I'm pretty sure that all Clan Related stuff is done with on Ghosts as there is no way to administer your clan now that the App is no longer there.
