Good luck with that!
I strongly believe that they (nordeus) have set a 50SKP limit for some reason. If they decrease it to 10/20SKP then everybody would train/teach their players 3 multiple roles and all teams would have a squad full of them (even the TM would be jammed with them).
I rather see them change/decrease the gap between the additional *. Like instead of 75SKP, there would be 50SKP. Every 10SKP is 1Q, 10x5: 50 = *
