It used to be very populated. Now, it’s not even at 100k anymore. Please 343 add a good ranking system and more maps. Do whatever you can to make the community happier.
Add better playlists, social/ranked playlists, a ranking system that you can actually see, some re-balancing, some tweaks, and better custom game options and this game will be perfect and will pretty much fix what was wrong with Reach.
More maps can come later, it’s not that important compared to the things I just listed above.
If you wish to discuss populations, https://forums.halowaypoint.com/yaf_postst183468_Daily-Halo-4-Population-Thread.aspx is the place to do so.
