In our recent campaign, where one of our players who had never Dm'd in 40 years wanted to DM B/X (after several years of playing in 5e), I rolled up a Fighter - S: 12, Int: 9, Wis: 9, Dex:10, Con: 10, Cha: 11. It was 3d6 x6, two columns, but I think he allowed us to assign. This was my "better" column. Not a single bonus to be seen.
He made it to 5th level with his +1 Sword before the campaign stopped.
I know that stats and bonuses nowadays are inflated from B/X, but I had a blast playing a bog-standard fighter who wasn't going to bash his way out of much, so I had to get creative.
