In my opinion, 343 should focus back towards halo 2 and 3 instead of the reach feel. Armor abilities and low jumping annoy me, it was a nice twist but I think they should go back to the classic stuff. Also, PLEASE make the campaign good. The Halo 3 and Reach campaign were only like 9 or 10 levels long and some levels were really short. Please continue with the skulls and scoring but make more levels, so that beating it on legendary is a real achievement. And mythic is next to impossible. Also make a better ranking system for matchmaking, Arena is cool but there is only 1 playlist for this ranking system! And to look at other peoples skill levels takes too long (Arena medals), the actual ranks are based only on experience not skill. I know Halo 3 started getting dumb with the boosting and all that but try to find a balance. I suggest, temporary bans for over quiting in ranked but stick with the 1-50 ranking system instead of the medals (onyx, gold, silver, bronze, iron). Also, bring back file shares they got abandoned in reach.
