I can only agree that changing the slayer cards during an event's duration, even if it is divided in halves, is simply uncalled for. It's nothing more than "Hey, you spent a bunch of money on those tickets so you could be stronger. We thought you liked that, so here, do it again if you want to remain competitive." This game is looking to be the first one I'll drop in favor of a new game. I don't mind buying a few tickets and maybe getting something, but I absolutely hate that what I do get is rendered useless before the event even ends.
