So, I think there is a 0% chance they don't rotate out sets 1 and 2 within the next 24 months. I just figure they'll introduce a legacy format at the same time, and PvE will always be everything. If they don't ever rotate blocks out, the competitive constructed meta will become untenable pretty quickly. I was, perhaps wrongly, assuming they were going to follow the same model as magic, considering how closely they adhered to other play formats. Set rotation also splits the playerbase between the new sets and the old sets, which for a game of Hex's numbers, is probably a really bad idea. I kickstarted this thing with the goal of having a collection I could build from and trade with to keep current, which so far, has worked really well! I hate having to play the AH so I can enjoy a competitive game without spending huge amounts of money. If they just say "No, you can't use Vampire Kings" anymore, my collection will be not only be worth way less, but I'll have a much lower incentive to keep playing honestly. Plus, if they rotate out set 1, the hell am I supposed to do with all these set 1 cards? In magic I can play Modern or Commander or any of those variants with my older cards. Given that Hex sets are somewhat slower at the moment, it seems unlikely there will be a rotation anytime soon. Hearthstone only very recently introduced something like that. I have, probably wrongly, just kind of assumed they aren't necessarily doing the same block rotation thing.
