I'm really not into this whole "customize everything and make multiplier like storymode" shit. Fuck all this custom armor perks and colors and alt armor pieces man just let me fucking snipe some kids 4v4 style no bullshit. Fuck out of here with this Call Of Duty scoring bullshit too man, I'm getting more and more disappointed by the minute. MLG mode better be the battle rifle straight with no armor mods and leaving that stupid shit to casual players.
Armor abilities actually look decent this time compared to reach, they look balanced. The point system supposedly was revamped so everyone on a team could get points without having to only kill or score the flag. I still feel like its halo but just evolved. I can't comment on the mlg because i've never been pressed about it. There are so many more weapons this time idk what they would give you mlg guys. Looks good to me so far.
