How are these MVP players selected?Are they selected randomly or by a BB or a GM?
they are decided by a algorithm, with probadly a bit random involved but normally u could understand hthe decisions.
On what bases are these selected
Mostly stats, but it seems totals are important so having some extra games helps.
Are the home country players given preference over players transferred from other countries?
I don't know it, i wouldn't rule it out but it isn't a very big criteria the same goes for the NT players.
Are players of team winning the league given preference
in my league we never had an MVP of a team who missed the PlayOffs, and normally most of the players voted are from that team even when there are good individual stats from players with less succes. So i say yes.
Hopefully i could help a bit
