I'm leaving the Battle Frontier. No one new has offered to join or challenge it. If one of my Frontier Brains, Kyrl and Sam want to run it, that's find by me. But as far as I'm concerned, it's time to move on. I want to take on the league. Maybe I'll revive it one day if Sam or Kyrl don't want to run it. But as of right now I'm giving up on it.
