In a perfect world all atributes would affect our character in some way ...
So you are forced to ballance out all our stats instead of regular 3 + Intelligence (or/and Wisdom or/and Charisma) ...
Bcs in this scenario Wizards (or/and other casters in case Sozz descibes) get advantage from char. creation.

I would like to see some ballance here ...
If at least Int 10 (wis/cha) is needed for our character to talk properly ...
then at least Str 10 should be needed to jump across all those gaps we have on map (like that crack in the bridge next to blighted willage, or those stones in water) ...
then at least Dex 10 should be needed so our character dont fall prone every time they jump with possibility to fall from the edges ...
and then at least Con 10 should be needed so our character dont get Exhaustion after few minutes of walking or after (or even better in a middle of) a fight.
