Okay, why are you even complaining about access to all specializations? It was originally going to be an LE exclusive bonus, but 343 gave that away, as well as pretty much every other LE bonus.
Half-Life 2 deserves its place, Halo 4 is the best 360 game, but defiantly does NOT have the best graphics. And if you ask me, Borderlands 2 shouldn't be up there at all.
