Adalanar: Hurray - I qualified - and I am very happy to be able to play.
Congrats!!! I agree it's kind skewed for people who begin the VT in a certain tier and advance through tiers as the year goes on. It probably hurt many players, if in fact that is what happens.
But, the only way around that would probably be to play ONLY the 2 rounds per month and hope WGT doesn't bump you because of winning, no matter the rounds played or level. And because the Pros/TP's/Masters have so few minimum rounds, I don't think they could avoid moving up at all.
Anyway, good luck in the finals :-) Might be your time to shine.
