So, pretty much, the only part of the Frontier you've actually taken are the names of the buildings and "Frontier Brain" instead of Gym Leader :s You may as well have just named them "Mav+Cap's Fake Gym 1/2/3/4/5"
Even if it was something simple as "Battle Arcade has to have a luck-related roll every X turns" (idk if Battle Arcade is luck-based, but I'm guessing) or "Battle Factory has to use Rented mons" and then the Brains can add whatever the heck they like. Otherwise, it just seems like a huge mess.
Also, if we're being technical, Pidge has no place of power in your Frontier. You clearly said it was not an official affiliation of the URPG, and clearly only listed you and Captain Dude as the moderators. So if he doesn't like a rule I make, tough noogies. Sorry, felt that needed to be said.
