There's no fine-tuning with the options you've given. Changing a slider (in PES) up or down by 2 or 3 does have a noticeable affect on your team, why would anyone want to dumb that down?
Why 'dumb it down' to 20? You could adopt FIFA's 0-100, then you can really fine tune to your heart's content. No? Then how low would you go? 10?
I don't believe that such a high degree of fine-tuning is realistic. Football is not digital, it is not measured, described or thought about in such subtle percentages.
I'm seeking greater contrast, so the available settings are more distinct and therefore recognisable. So the different styles you encounter are clear, not muddy.
Finally I'm seeking something more intuitive and easier for newbies to read and grasp.
I'm trying to think of the easiest way to quickly explain how players play, not just their attributes. Not sure what the best way is; should something be overlaid on the pitch to show the sort of areas of the pitch the player will cover, including runs infield and indication of work rate?
That's what I would like to see too.
Work-rate has a big impact on how that player will behave on the pitch, so that should definitely be included somehow. Suitable positions too, obviously.
Perhaps a shortlist of their highest/lowest rated attributes, their strengths and weaknesses?
I think the Specialities need to be re-thought. At the moment they are based on attribute scores, so if you have like 86+ (or whatever the number is) for Short Pass & Vision (or whatever) you get the 'Playmaker' speciality. This means only the top players have any, which sucks. I think it would be better if they changed these so that they are calculated in relation to the rest of that player's attributes (or in relation to their OVR, whichever works out). So an average/poor player could still be described as a 'Playmaker' if his highest attributes clearly lie in passing and vision etc, rather than requiring him to be one of the world's best. That would give you a quick idea of where his abilities are weighted, which is the kind of info you need.
Ultimately, as I've mentioned before, I would ideally like each player in the database to be assigned a behavioural template, which affects their movement/tendencies on the pitch.
Perhaps Traits could be included here, although 'Long Throw-In' doesn't exactly describe the type of player they are, and again this relies on the detail in the database.
