I think even then class abilities enhancing the stats is what really makes those things happen. Going by ability scores alone, nobody is going to shine, because the bonuses don't matter as much.And because there are 6 attributes, and usually 4-5 party mwmbers...this usually means that each PC has their space to ve the star.
Picking a lock and sneaking past a guard? Rogue gettheiri moment in the Sun.
Arm wrestling contest to gain the respect of a barbarian chiwften to learn some vital information? Fighter gets to shine.
Need to eat in the wilderness? Ranger got you.
Need to interpret an ancient text? Wizard up to the plate.
Need to convince two kings to not start a war? Bard can keep the peace.
Balance comes from each character being different.
