You mean like the manga or the fighting game? Because the fighting game isn't great other than being a companion piece to the manga. I mean, it's "great" because it has beat-for-beat perfect manga panel inserts in the fights, not because it's actually very well put together as a game.
Anyway, to me, Quantic has a loser's philosophy. A winner's philosophy is to say, "Because we lost, we need to train harder and make the necessary adjustments to become a better team. We need to practice against the best teams until we can beat them."
A loser's philosophy is to say, "Because we lost, we should go find weaker teams to play against who we can beat."
I'll admit, I'd rather have them than Dignitas or Velocity, and probably even Curse or CLG. I wouldn't really rather have them than the other Challenger teams they were competing against, though. I suppose a better way of putting it than, "I don't want to see them in NA" is "There are three teams in the Challenger circuit I'd rather see make it into LCS than them" because I'd still take them over the busted, complacent-ass teams we have wasting spots here.
