I've seen similar things happen, except the second person was even worse. I don't see the point of having one person being significantly less capable because of 1 sequence of bad rolls. Especially when the person who rolled poorly asked before rolling if they could just use variant of point buy (this was pre point buy).Rolled stat imply luck.
Ok, you can help people to catch up, but what to do with rolls like
18, 18, 16, 15, 13, 11
vs
12, 11, 11, 10, 9, 7
just figure out how your proposal will react with such rolls.
