I just realised and learned that some special abilities are useless, and I ask myself why are they still there or not imporved;
-->One-on-one goal score: is not that effective it just depends on how skillful your player is.
-->Defensive wall: not that useful, I don't have much to say about it.
-->Playmaker: what is it's use anyway, because when it's active any player can intercept their passes, I saw it happen many times.

But I consider Premium special abilities from Special sponsor to be very effective; probably the reason for that is sales; so that we can buy special sponsor.
