Before this gets locked, I'd like to voice my opinion:
Stop getting so damn worked up about this. You people who keep saying Mono is 'easy' are missing the point entirely. There actually is strategy involved, but it's a completely different strategy from the ones the 'main' gametypes use. Basically, Mono is for action, everyone else is for puzzle. Some people like one, some like the other, and you need to have a balance.
