I've read through the posts and this is looking like a game of Pong.
From my perspective here is how I see the argument:
Dut: You can still play Block 3 at your store. No major tournaments were coming up post Gen Con and pre original rotation, so this shouldn't have been a complete waste.
Tainted: The rotation was a surprise. Tainted's group plays competitively. They don't have the money to buy SC4 and SW1 right now. They feel jipped.
My opinion: The argument that the rotation - in the way it is being done - will hurt the players is hyperbolic. The four dot cards that would have been legal in September, would not do you one bit of good at Nats next year. Therefore the rotation would not hurt tournament prep. Also prize support is still being given to block 3. So I don't understand the issue.
This pisses me off more than anything - just because a rotation happens (whether that is in RPG or CCG), the cards rotating out do not instantly disintegrate. You will just have to trust me on this. I currently have a number of Mark of the Beast from SC4 (whole cards not dust) that was re-released as promo cards (and no they did not just reconstitue). Suddenly those cards became standard legal again. Understandably most won't be standard legal. Ever. Which in some cases (BRT) I am really fine with.
So Tainted - if you want to go to L5R - peace be with you and hope your experience is better than the one you have had with UFS.
