Like I said, just use Video game logic where Super Sayans aren't that big of a deal, or just inflate everyone else to be on par with a super sayan to keep it balanced or don't even bother with power levels in general, and instead deal with who is the most active in the topic instead. Even then, its a PvE RP instead of a PvP RP, so yeah...

I mean, power levels are complete BS anyway, and even the show points this out. I mean, what, 4 months of training and Frieza can be on nearly equal footing with Beerus? yeah I don't think so.
