Being forced to purchase a new core set to continue playing tournament play is totally unfair.
A cynical person might say FFG is happy forcing this change in order to sell more core sets. Include the fact that there have already been a few forced purchase updates like Rebel Aces for AW's or, worst of all, the Raider for TieA's.
I don't care about the new core set, the new T-70 or the new TIE's, and I certainly don't want to be forced to buy them to continue playing a game I have invested significant money into.
I don't believe a company like FFG, with talented game designers, couldn't come up with a way of allowing all players to participate in X-Wing Organized Play instead of excluding those unwilling to buy a new core set.
