I couldn't vote. I'm somewhere between needing a 16 and needing a 14 (every character doesn't need a 16, but I think it would be difficult to play a character whose highest score was 14 (assuming every other score is lower)).
For instance
15,14,13,12,10,8 is fine and I have played before.
14,14,13,13,12,12 is fun for a well-rounded character.
I've played higher than the Elite array, but not lower than the above well-rounded character (although I have played with stats lower than 10 often).

Edited: I looked at the point buy and the well-rounded comes to 30. I've played 28, but I wouldnt want to play lower than 29 pb. As others are saying, its relative for some people, personally it isn't. I played a dwarven monk with a 10 dex amongst players whose lowest score was 12 (and highest, 18) and I impressed them because I knew what to do with what I had. My highest score was a 16, in con IIRC. And for my characters I like to generate my own scores, based on the background and personality of the character.
