When's the next tournament? I'm trying to stay under 80

We won't know where they are farmable until they let us know. Im hoping that as most people hate tournaments and hopefully there will be enough competion from the new star wars game - force arena they make them easily farmable.

I have only played force arena an hour or so and already have characters from the rebels tv show and rogue one. I would really like these in GoH but there are no rebels in the game and the rogue one characters are tournament only so I was not able to get any of them.
