Is the brawl event a one time fee? Or do you get knocked out and have to repay?
These rewards can only be earned once, but don't worry—you can continue playing in the event beyond five wins.
This leads me to believe it's a one time fee, but I would rather be sure. If it is a one time fee it's definitely worth it and I'm excited for it.
One-time fee. Wins count towards the rewards, losses are ignored.
