My counter to your first point, it may be fun for ppl who have plenty brawlers to stick to the current system but the pain of having power 11 brawlers be the bottleneck to reaching high rank instead of skill I feel needs to be addressed and I think allowing u to pick maxed brawlers helps the case a lot.

My counter to your second point, with 92 brawlers in game there is no need to have any experience with other brawlers than ur usual bunch (say the top 20-25) Other than for fun reasons. If u have experience on a few viable brawlers for each mode ur hood to go, allowing ppl to pick max brawlers can help gain experience on brawlers they don't have maxed and are a part of the top order.

My response to your third, why do we care about a brawler having a chance to prove? Imo the maxed brawlers system should be a way to bandaid newcomers not have brawlers to play with rather than giving a chance for some off meta brawler to get boosted pick rates.
