Duel Armor abilities (sprint is always on)
No duel weapons
Drop in and out Multiplayer co-op Matchmaking
AA's and pick ups
DMR
I agree with everything but these.
This is why I think so..
No duels - I feel like if there was that MC would have had a 2nd weapon attached to his side, Obviously the weapon he has in his hand is a modified pistol so why only one? probably because if he had two it would be over powered. This makes me think that maybe more than just the pistol can be modified which probably means no need for duel wielding.
Drop in and out MM - Afking is more of an issue now. This may just be due to the cR but I think everyone always wanted to join a friend while they were in the middle of campaign and we have all felt the sting of someone quitting in the middle of a match, playing a 4vs1 isn't fun and I think 343 knows this.
AA's and pick ups - I feel like some of the AA's are going to be forgotten about and replaced. I think the bubble shield, mines, power drain, portable turret, drop shield and maybe some new ones will come back to Halo. IMO you will be able to throw a bubble shield on a man cannon and fly up with it while using your jet pack or while clocked throw a mine down in front of a warthog...
Duel Armor abilities (sprint is always on) - We have been given the taste of fast movement! I feel like the game moves so much better with the ability to run and I think 343 has taken notice, running is almost a FPS must have and I think sprint will be a slandered ability. I do think it will still have a cool down time but I do think it might be possible to run while jet packing, cloaked, or new AA....
DMR - I think although similar the BR and DMR are totally different weapons and both have there own cult following. I feel like both weapons will make the cut or a new BR/DMR highbred BMR single fire w/bloom ALT fire 3 round burst (less accurate).
