Too many inexperienced people flooding in and ruining games for the rest of the serious community! They're burdening friendly and enemy teams as clueless engineers, horrible gunners, and wrecklessly uninformed captains with ludicrous load-outs. Not to mention every time you get rightfully enraged after trying to inform their insubordinate asses of what to do and then ask them to leave after they fail to cooperate. Somebody always wants to stand up for the idiots to defend them simply because they're new.
Those people are usually the engineer or captain of the enemy team who only play with well-known, and experienced friends who have mics.

MUSE has already stated on the front page that the "Quick-Matches" will be turned into "Novice Matches" and the tutorials will be worked on to train up the newer generations of GOI players, to protect the pros from being nuisanced by casual gamers who want to play in a laid-back manner (Because they haven't lost enough to want to win yet. They're just losers who happen to be in the earliest and worst stage of their gaming lives, and are hurting the community for it.)
