Maybe have a inverse perk system to let those with lower skill into the bigger arena? Maybe charge a percent of total perks in the pool, or charge according to rank, with lower ranks having the chance to enter a bigger brawl, while the elite ones can have smaller fights? Dunno. It's frustrating to wait in que for the arena my squad is in...
The reason I'd want an 'inverse' relationship towards the player's rank and the ability to enter the busiest arena, is that I find the players at the top of the food chain entering these ones merely to increase rank. Whether by cherry picking, vulching, or just hording it with others, they're drawn towards the biggest chum trail...
Plus, would get them to spend some of those perkies saved up. I'm tired of hearing "Oh well, you killed my 262. Down to 11,000 perks now..."
