I'm imagining the economy already being raped by that. 500k each player from that team? Let's say USA wins (USA being the most numerous country from the community), do you want to give 500k to all americans?

If you give a rule like max players in that team to be 3-4 max players maybe it will work, but better, teams have max 3-4 players and that 500k is split in 3-4 for those players instead giving each. (ofc maybe i understood wrong what u wanted to say)
