and I don't get it, why would that be bad. some players are faster, some are better driblers when you get them etc.
stoo why not build up on that, emphasize their "natural born" skills rather than fight uphill to make every other white skill as as good as those few.
take them as they are, if that makes sence.
the only proven relation between individual, white, grey or whatever skills and the performance of a player is only the mutant players.
1st generation (those with 1500% skills) or 2nd generation (with 340% +1% skills) has some visible effect in a game's result.

The rest are personal perception (and maybe imagination).
It's impossible anyway to prove any theory because the conditions are different every time.

Of course doesn't mean that I 'll put defending skills in my attackers
I 'll do the basic "right" things but without great expectations from that.
