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...
Or they could just change the system so the tier unlocks with the required number of tickets (gating still in place) - but a loss or bug doesn't cost you more tickets (players happy). Problem solved and win/win. But that's too simple. Sometimes it seems as though EA is only happy with win(EA)/lose(player). Poor design and nothing done about it. After playing this game for 5 years, we should all be used to this kind of thing by now.
