If everyone was happy rolling, then let it ride.
Next time, I would give players a choice -- point buy (incl. the default point buy, ~ array) or roll. BUT: if they choose to roll, they shouldn't get a sop if they roll low. You take the risk, and (as they say in playschool) you get what you get. If you're not prepared to be under-average (and, frankly, 30 points is just fine), then use point buy.
