I think 343 should change the physics for the game to resemble that more of Halo 4 and the changes 343 is throwing in there, to show that Reach can in fact stand on it's own as a game, since Halo 4 is simply expanding what Reach had already started to do; I think it would've been better to call Halo 4 ---> Reach 2. Not that it would be a bad thing necessarily, I highly enjoy Halo: Reach (to this day) and unlike most of the gaming community I 'get it'. I like having encounters be meaningful and directly affected by moment to moment reactions.

AA and weapons wil be the same as in Firefight.
I say give Reach it's undue respect, and provide fans with a true unadulterated experience that Halo: Reach was in fact to become, but hadn't realized due to trying to please fans while exploring new possibilities in artistic direction. I'm sure once people try this new reincarnation of multiplayer matchmaking it will be a great game. But anyways... I guess feeling hopeless is expected from this generation IDK. ):
