I will disagree. If you have had any min/maxer in your games. You'll see that they, invariably, follow the same path. Starting stats: 15, 8, 14, 10 or 13, 12, 13 or 10. If variant humans are allowed 1 point in strenght, and one in the 13 where ever it is. (int for the eldritch knight variant, cha for the blade lock variant). Already two different choice? Wow... Again a counscious choice. If you keep the fighter a champion or a battle master it won't matter. Progression will stay the same from one character to another. Yes with the right background, the right player differences will abound, the logic behind the progression won't.
The feat taken will be obviously GWM. Then level 4. ASI into Strength. Level 6, ASI into Strength again. Level 12. ASI into Constitution. Level 14 ASI into Constitution, Level 16 ASI into Constitution again if the campaign goes that far. May be the Tough feat could be sneaked in somewhere.
But take the example of a player who rolled. 14, 15, 14, 10, 6, 14. Ho man... my life is broken, I wanted to do a great weapon master and now I am stuck with a bad array... I'll do one anyway. Stat placement Maybe St and Dex? Feat? Great weapon master. The player starts as a great weapon weilder. Maybe along the way he'll chose medium armor master? Raise is St and Dex at level 6. Dip into the warlock class to get a bit of an extra whomp for a few levels. Now I can imagine a player making a pact to get power and going to every extent possible to find those gauntlets of ogre's power. Some items becomes quite important when you know that the high strength is not that reachable. A 16 might become satisfactory.
A set up like this can bring great role play. Even a totaly perfect beginner will have to role play it through. Especialy if the DM demands a Role Play reason to dip into an other class. Here the player would be more or less nudge into the warlock or sorcerer style. But what if he chose paladin hood instead? He could get an other fighting style (probably defense). Would get the lay on hand. Who knows?
Yes you can do that with the point buy. But you probably won't do it unless you are an experienced player. Most novice will stick to what they have. Race and Class min/max attribute can give the little nudge they need to get into it.
I have two min-maxers at my table, and neither of them play variant human (one is a half-elf, the other is a goliath).
The player of the goliath character picked polearm mastery as his first feat.
