I don't think Halo 4 could become MLG because 343 added abilities that are in my opinion *for noobs*(exemple: Promethean Vision, Hard Light Shield, Auto-Sentry, Regeneration Field.).With thoose abilities, It is very easy to do kills in matchmaking.Don't forget that 343 added too much powerful guns( Inciniration cannon, scattershot, sticky detonator, rail gun and a lot other...).Because of thoose things it's so easy to do kills!
