I think the campaign was slightly disappointing, and in MP the maps were somewhat repetitive, but honestly, those are small issues. The MP will not flat out die like in 4, and with the updates adding so much more things like reqs, camps, armor, an new maps as well as controller customization, it could be fixed very quickly. I like the last of armor abilities like jetpack and armor lock like in Halo Reach. Everyone has the same abilities, and if you want a more even balanced game you can play arena. However, the campaign hype was obviously unfortunately a lie. There's was like barely any confrontation between locke and chief, and it really felt like nothing got done, nothing answered. However, i would rather prefer a good mp experience to campaign, since campaign does not really decide the longevity of a game, since it lasts shorter than mp, and with the updates coming out, 343 has truly learned from its mistakes with halo 4 and are definitely committed to longevity in this game's mp.
