I'm one of those who won't play a D&D campaign where rolled atts (in the sense of rolling for how many points or direct rolling of atts) are used; atts are too important under the 3.X and 5.X game engines, at least at the levels I'll play/run.
It was an issue recently; one of the guys showed up with a character with two 18's and a 16...
Mind you, I'll use the Redric method - random assignment of points - provided the points are kept limited.
I make exceptions for Traveller and T2K... but I'll note that T2K 4E, rolled atts can be WAY overpowering. Had one who rolled AABB. She was very much more the main character than the much more interesting one who started with CACB ... (A=d12 B=D10, C=d8 D=d6)...
Then again, that latter lose none to aging, and had half a dozen specializations outside concept.
