I'd be amazed. BB-Charles even said that with multiskills the wages would actually be lower than when a player is briliant in 1 or a few skills.
So I doubt a 4 times (ID,IS,REB and SB) strong (level 8) would ask more wage then a 2 times level 10 (IS,REB), 1 time level 11 (ID) and 1 time level 1 (SB)...
And if you take a player with 1 level 15 (eg IS) and 2 times level 8 (like REB and ID) and 1 time level 1 (SB), he will ask more wage still!
I might doubt between the first 2 players, but eventually go for the first to play in my team, the third here has no change at all to get chosen by me...
They are not your friends; they dispise you. I am the only one you can count on. Trust me.
