I used to spend way to much time rolling in the original games.
I hate the concept of dump-stats, but felt that having low main stats would be crippling.
That is actually my main gripe with point-buy, it leads towards focusing on the most important stats and ignoring unpopular stats.
What I would like is to have the standart array, point buy and 3-4 rolls. You role your stats, can see all of them and then decide if you want to go with one of the rolls or if you use point buy/ standart array.
