So the concept is simple, decrease RP by an amount after a period of not playing in a tournament arena only if its over a certain value (say 1600 for now). The concept's the same thing from League of Legends, and you can fancy it up with different ranks, prizes, etc.
These are the pluses and minuses I see:
+ Encourages people to play to maintain RP.
+ Prevents people from building up RP and sitting on it.
+ Can make top RP standings less static

Not saying to put it in, just would like to hear people's thoughts.
