The average youtube viewer who posts in ever single Halo 4 video has NO CLUE as of why Reach failed.
They just spam all videos with ignorant comments with poor grammar like:
"uh i dunt know i relly liekd Reach and armor lock wasnt that bad i mean u just waited for him to ppop out"
or
"Ordnance was in reach so its not Cod. halO 4 is a mix between halo 3 and 2."
Have you found something similar, or am I the only one notices this? If I am, then I don't even know what to say. There's a reason why CoD took over youtube and Halo didn't, but that's another story.
