Hello,my question is : The players which are having special abilities (``deffensive wall`` for exemple),are really better than the rest of the players which are not having those special abilities?

Here`s an exemple: Let`s assume that i have a player with : 85 Deffensive,50 Offensive and 70 Physic@Mental (random numbers) + Deffensive Wall,and another player which has exactly the same numbers but WITHOUT special ability.

Which one is better and how big is the difference?

Thanks!
