Rant about Leaks

Who the f started that shit about you only needing utot tokens that you'd get from the event to exchange for Utot players, I shared almost all my 115's 116's and 117's for fear of them reducing in value before this event, now I'm seeing that I need them for exchange, had to buy the 117's and 116's again. I could have gotten 2 utots or a utot and a high ovr player. I'm so pained f this. Why can't they just release requirements before the event.
