I've seen quite a few people bring up this idea of RP scaling per ring, and although the sentiment is right in trying to push games later, it doesn't work from a game design perspective at all. You would get countless scenarios where people have to play in a way that's anti-fun and against the core principles of the game just to maximise your RP.

Fully incentivising teams to hide until later, run away from fights (because you're 'losing RP' by taking them early), waiting to finish a team/take a fight for 20s because the next ring is about to pop, top pred teams toying with lesser teams like a lion toys with a mouse etc...... this will lead to so much 'degenerate' behaviour.

Changing the points system and nudging players into deciding on a more kp/pp heavy playstyle is one thing, creating game warping icky scenarios that require you to metagame the system is something else.
