Tbh I didn't thought that someone would think in use a 1-3* sub xDDD but the limit of avq for subs is till 120%, so it could be 1 rule for the starting 11, without any 1-3* and subs till 120% including 1-3*..
Still but, I would prefer to eliminate these kind of players 1-3* and 9* and stay inside the starting idea.
Maybe is that you haven't 4*-6* subs?..
