I know what you are talking about but the problem is a misunderstand you make about what 1% mean ...
It is a value which convert a number we had in the original old top eleven , for example at level 1 a player reach the 6th star ( 100% ) at quality number 25 .
This quality number still appear today for the team's overall average in the other/ opponents or friends manager's profil windows . It grows 5 by 5 for each levels , so at level 2 a player reach the 6th star at quality number 30 .
So basically if you play top eleven in the original way , i mean try to level up each seasons , 1% is quickly reach for any skill's quality number that is not a white skill .
Return to the old system without % but quality number and the perception of the game is very different .
Messi could have shooting skill quality number 26 and marking at 17 on level one and then 10 seasons later 90 for shooting and 37 for marking ( 1% would be showing for marking skill with the actual system long before the 10th ascent of levels ) . So 1% isn't so strange and illogical with the old system point of view .
This is like that , each roles has required skills to be ( more or less regards hidden skill ) a good players ! Everybody can debate about which skills should be required for every roles ... Nordeus fixed the rules , we have to follow it !
So this is inherent to the levels system of this game , a player can play 14 - 16 seasons and go up 14 - 16 levels without training non-required skills as much as the white ones .
Fixing skills distance limit between groups attribute like before will force players to be trained on grey skills even more than today . And today you already need to train greys ones to have a better progression of the white ones ....
Objectively , this doesn't need changes , you just have to learn how to train in the best and efficient way each roles in a team .... ( making good combinations of drills ).
And for old managers who start playing this game with the old top eleven , most of them seem they still not adapt to this new top eleven and his sucessives changes ( 2015 to 2019 ) .
Adapt and tame the rules before asking for changes because you are relunctant and/or you don't understand it ( this is adressed for a group of peoples , anybody in particular ).
Other sides of this game need changes ( like limited the abuse of tanking in the length , upselling possibilties) , but not this .
so what ? My good trainings must not be rewarded ....
I take time and efforts to elaborate good trainings and a good management of the whole team each seasons , so it makes me thinking it is normal peoples who don't do this as much as me have big difficults to compete against me . You need to understand this too .
