I like Halo online, I just don't like Slayer DMR because everyone starts with these distinguished mentally-challenged power ups (armor lock, camo, fucking jetpacks) like they're nothing. Slayer Pro was good because it was DMR start with only sprint and none of those stupid abilities.
Team Objective would be good if they didn't have awful gametypes like stockpile and headhunter and hot potato come up constantly. Needs way heavier weighting on multi flag CTF, 1 flag CTF, regular Oddball, and king of the hill
