I don't know if someone else already asks for a ranking.

Implementing a global ranking can change a bit the way to play that some players have in this game. Not playing with money let people plays Allin with everything (and maybe win with everything)
If there would be a ranking where people takes points for placements in tournaments maybe they will not play in that stupid way ... because they lose places in the ranking. And then maybe the possibility to open tournaments only for 100 best or something like this so that the game could be similar to real poker.

I hope you understand what I mean
Thanks
