I think that there should be some good (trained) special attributes for defenders, as now expect corner stopper (which a team doesn't need more than 1-2), rest are usless.
Also something for strikers (cause now expect the sharpshooter, which is decent attribute but very expensive and now after the less goals change, is much less effective, there is nothing).
Midfielders have enough attributes I think (though of course, the more the better).
Maybe something to keepers too, but big passing bonus seems a bit usless to me...
And in generaly, I think the attributes should not be that clearly good and must train, (like playmaker for AM), but should be with advantages and disadvantages (like sharpshooter) so a manager will choose what to do, and won't be that clear decision.
I also think that we should have some more "natural" attributes, powerhorse seems fine, maybe some more.
