Why not though? What difference does it make? They play less games and usually the top scorer may get 20 goals if they are lucky. Besides I thought you wanted random fun picks.
These are not game breaking players.
Other than Poland what is wrong with the other leagues?
Russia is somewhat pointless as its a low scoring league played at weird times. Belgium is actually stronger than The Netherlands and Turkey and Portugal has always been available (Nobody ever takes Turkey...)
At worst drop Poland and Russia and I dont see any issues at all then.
