Thats my first option, but i change it to see how it works better, in my second Team i also use my 5*DC, is pretty good.

I have a FKS but is special ability does not work. For what i could see in this 3 months, SA only seems to works on 5* players or higher, unless you are playing against very weak teams.

I still have to learn a lot, but i am trying to find out what are points of quality that makes the player for some kind of SA, because player do not grow in the same way. You can give SP to defence, atack or FM but can not choose in witch of the 5 parameters to grow.
So i am trying to find out, who that happens, i started with the scout list, since they all have SA created by the system, but still did not manage to find any conclusion.
