I posted this over on another pes gaming forum but i thought id post it here too.
They should stick with the same principal they have but improve how the divisions works ..Example of some kind of tier system and a larger difference in ratings required to move up into the next division.
Tier system example
DIV 5 = only allowed players with a maximum rating upto 70,
Div 4 = only allowed players with a maximum rating upto 75
Div 3 = only allowed players with a maximum rating upto (possibly 85)
Div 2 = only allowed players with a maximum rating upto (possibly 90)
Div 1 = No restriction of what players can be purchased
If you move from div 5 upward the money you have stored can be then spent to improve your side but if you fail to stay in div 4 you must then sell these players so you meet the requirements to play in div 5 again (in real life you wouldn't see Ronaldo, Messi etc playing in DIV 5 so it should be attempted to show some realism in game).
The amount of star teams sitting in div 5 for tbh an easy time is shocking and makes the game no fun at all (i couldn't even imagine how a new starter would feel).
Overhaul completely and i would suggest going down the fantasy football route (start with X and limit the amount of stars that can be bought). I much prefer my opening option though.
