Hi dear GM-Perpete,
Thanks for your answer,
Its in fact the "third" interpretation,
A player could still play for NT (U21 included) if injured, and an Injured could play on Thurday but only if Friendly!
12th Player could be a different player, for a different Strategy perhaps. Maybe its not a good resolution for AA, but its good for U21, or maybe inverted, i dont have a closed opinion about it.
To be really honest, i really think that NTs and not for every player, so if you have 1 player on that, means your player is the best or one of the bests, and that should me more rewarded!
About more games, just wanted to know if that are in a radar of the Staff.
Best Regards,
Baverone
