Thank you. Yes I've understood it better now. Sorry, English it's not my native language and sometimes I miss a few things.
Of course its always better to have full bars, but training attributes that I don't want them to train, either because I think they aren't necessary for my playing style or because they're already too good at them (or too weak that it's a waste to spend CA there), just to fit to the role they play its something that I admit I never did, because I didn't know, until recently, that the only way to get that full bar was to train the same role they play.
