I don't think you realize how small the gap between tier 1 and tier 2 is. In the off-season, when we had teams from both tiers facing off, a heck of a lot of games were down to the wire, especially when you looked at teams like Oxygen, MxS, and Rare Atom, for example. A lot of world champions have actually gone on to play in tier 2 leagues. At the end of the day, what league you're in just comes down to the org you play for.
