I believe that duel wielding should come back into halo. It was one of the most fun things from halo 3 also the smg should return it was one of my favorite weapons ever... Of all time. Lol but seriously it should come back it was freaking awesome! Also the Personal AI system would be really cool possibly annoying but I'm willing to try something they need to add equipment back like energy drain. Another thing they need to bring back would be the missile pod, flame thrower, and the special grenades from halo 3 man that game was the best! Some weapons from halo reach I didn't mind like grenade launcher and the plasma rifle is gone! I've been able to use that since the first game! But some new ideas for the game would be awesome if at least one mission in the game you could be commanding patrols and platoons of marines and unsc vehicles from place to place like in halo wars but just a mission or maybe a couple that could make the game longer the game seemed too short to me and it should be a solid 12-18 hours to me if that doesn't seem too long to anyone the mission weren't lacking but they could have been longer or could have had more missions that's why I think a few missions like halo wars should be there for length and for a new way too play for those who haven't played those types of games before...ohh I just got an idea the halo 5 online should have a head to head halo wars type game type whether that be 1v1 or more but that would be sweet so this is cool if anyone reads all this so bye
