When I started in B/X you rolled IN ORDER, and part of the challenge (and FUN) of the game was creating a character you wanted to play, weighing the balance of taking 2 from one score to bump another by 1, etc., and working with what you had to work with to make something great.
Moving on to AD&D, with minimum requirements for many classes beyound the generic "9 base" made getting those classes when you rolled in order a treat, something awesome and unique, and more enjoyable IME.
Now, with point-buy and standard arrays, and arranging to taste, you have dozens of PCs who seem almost like carbon copies in play. What fighter in 5E doesn't have a STR 16 (or better) by level 4 for STR-based builds? How many rogues are played with DEX below 14??? Ever? When players can move ability scores around, it is just another step towards homogeny.
Being closed-off to what might be when you fate take a hand really is a pity. If you're happy with it, great for you, but it's your loss--especially if you've never even tried it. After all, you'll never know just what you'll get--and even with the way I prefer to play, background and class are still up to me--as is every other choice I make as I advance my characters.
