It feels ridiculous that a player can develop from say 77 to 90 overall and have 0 playstyles at 90 overall. Playstyles should also accumulate with growth. Think of how with madden superstar players unlock ability slots with age. I think all players should have at least 1 playstyle to make them feel unique in some way to other players with the same ratings, as they grow they should accumulate more. My thoughts:
Overall Rating 60-70: 1-3 playstyles
Overall Rating 70-80: 2-5 playstyles
Overall Rating 80-90: 4-8 playstyles
Overall Rating 90+: 6+ playstyles
Playstyles should generate based on players position and skills - if I have a CAM with fantastic dribbling - maybe they get technical when they develop to the next overall.
If I have a tall striker with good heading, maybe they get precise header next overall.
If it is too difficult to figure out - please just let us edit characters playstyles. We should also have more freedom to edit characters as is. Say I have the same player for 5 years, most players will not have the same haircut or facial hair for all 5 years.
Final note, pregens/regens generally ruin the gameplay of career mode for me. That combined with mediocre clubs getting way more money to spend each window results in teams like Nottingham Forrest putting out a lineup with nobody under 85. That isn't realistic...
