The accusation that it will mean players starting out with super high stats across the board is ridiculous - in reality, no-one is going to sit at their computer hitting re-roll for the literal hours on end it would take to get three 18s...
No, that's why modders wrote an autoroller for that in BG2.

Y’all underestimate patient nerds/geeks like me. I’ve sat there for plenty of time to get stats I want in BG1/2.
I think a roll system would be fine, just lock it after the one roll. Want to try again? Main menu for you. That’s IF they want to stop OP characters. Honestly, with point buy (and custom lineage if we get it) you can start with 18 in your main stat.
Roll, point buy, or standard array….I’m fine with any of them.
