Just as the static ASIs in 5e had the unfortunate side effect of type-casting a race toward favoring a particular character class, the static ability score penalty had it's own set of issues. Type-casting was one of them. If you belonged to a race that had a -2 CHA, would you play a class that relied on CHA such as the Paladin or the Sorcerer?I think that is where the old -2 came in to create some differences. An elf and gnome wizard might have the same int, but con and strength were going to be meaningfully different or the same with meaningful tradeoffs elsewhere on top of the various ribbons that actually distinguished the characters in play or build. By getting rid of the -2, 5e made different PCs virtually indistinguishable from each other the vast majority of a campaign.
