Eh, I don't really mind losing. Playing better people is the only way you can get better, and this system is what I've wanted out of Halo for a long time.
Humbling if nothing else, heh.
I agree with being humbled every now and then, but...
You only learn from a loss when there's something to be learned in the first place.
Losing due to a faulty team teaches nothing, outside how to waste time.
Furthermore, if the power gap between two teams is too large, it actually works the opposite way. People become fustrated and demotivated to continue.
There's nothing I enjoy more than a round (in any game, really) where it's close, and I cant tell who is gonna win or lose, cause then yeah, I'm probably learning, or at least meeting an acceptable challenge.
But losing again and again because the idea of map control is such a high level concept to your average player apparently, is just fustrating. Not humbling.
