If I had T for scout, I'd buy only MC. Main disadvantage of scout's skills are equal stats. Thats good only for MC.
Last season I've bought nordgen GK, 64 rating, (5* @L10) for few tokens. I've only upgraded his def skills and at the end of season he had rating 68 (6*), def skills 77. Now he has rating 70 (5* L11) def skill over 80. I wouldn't change him now for scout GK because i dont think i could find scout with rating 74 and def. skills over 80 and he'd be older than my nordgen.
Nordgen defenders and ST are useful too because I upgrade only def/att and physical. My nordgen ST has rating 65 (weak 5*) att skill 73, physical high too.
However, MC needs all skills def, att and phy skills, so it's way harder to keep him at high quallity.
My ex ST, not nordgen, but for me more useful than scout.
He has similar age, attack and physical stats as scout, but low (useless for ST) defensive skills and he costed me 1T (49T saved)
