Hey Mr. Eagle!
Brawls are an important part of the game, and I personally know players who don’t engage in ranked play but still actively participate in brawls. It’s a game mode that keeps them involved and engaged, so making sure it remains welcoming and competitive is key.
With that said i’d prefer option 2, but I’d like to keep the Adept in Fray 1 until Tier 5, that setup just feels better. Also, I think it would be better to remove Alpha, Beta, and Untamed from Fray 1. That way, Fray 1 would be super accessible for new players, making it easier for them to be competitive.

I’m not really a fan of the idea of rotating frays, could make things more complicated than they need to be.

As for the GF frays, it’s a complicated matter. As a guild leader, I know how hard it can be to fill those frays, but as a player, I also wouldn’t want to devalue the worth of GF cards.
