Special Ability - Useless or useful?

[Ljepoje]

x1 one-on-one stopper
x1 aerial defender
x2 corner specialists
x2 free kick takers
x1 one-on-one scorer
x2 shadow striker
x1 play maker
x3 penalty taker

These are my favourites, and the SA my players currently possess. Also, I noticed that my ST (SA: one-on-one scorer) manages to score goals on the given Free-kicks much better than my FK "specialists". So far, he scored 4 of 5 FK. He is my penalty taker as well (scored 2 of 2). Also, since I trained my DC/DR and gave him a SA as ariel defender, we stopped conceiving goals through corner-kicks.

Btw, good thread @dv8r! Should be a "sticky" one!
