Event tickets for galactic legends is awful mechanic. At least make it do tickets are consumed until you win. Blowing tickets on experiencing the event for the first time removes fun from the mechanic...
I agree that the ticket system is poorly designed. As Nikom565 argues, Discouraging gaming within a game is asinine. I also support the idea that it should be more like the Phoenix/Thrawn event: characters open the event, maybe need tickets per tier. Telling me how to use characters I spent so much time preparing is BS.
