Since the the way search in arena has changed it has become very hit and miss whether I can find games in some playlists. I’m a UK player and I can bet there isn’t a shortage of people playing at the same time, but over the course of 10 minutes I can go from finding games to looking at a red message saying not enough players. 343 need to sort the searching out. Never had this problem in any halo game including halo 4 which is 343s own game (obv). I can only play when my american clan mates come online restricting me to late evenings. Forget weekends or my days of work.
War zone still works though. Hooray…?
