I've personally used it to improve or disimprove certain players that I thought were overratted or underrated even tho they werent in my team, for instance, torres needed to be improved on certain occasions, also the 'godlike' adebayor' needed to be toned down a few notches especially on fm08. Others come to mind, agbonglahor, messi needed improvement etc. ibrahimovic needed toning down aswell. In my opinion this sort of use improves the game, some people get so anal about using editors, its only a game ffs. Also for a a few years ago it seemed like their was just a continuous arsenal 'bias' in general to the game, which in my opinion was not accurate enough.
