To borrow the same basic construction:
For me rolling stats has several advantages over point buying stats and few drawbacks.
1. Players can discover their characters which promotes spontaneity and helps players who develop ruts work their way out of them.
2. It starts classes with different degrees of attribute dependence on a more equal footing because there is no compensated stat dumping to boost single-attribute classes.
3. It might give a lucky player a little bit of an advantage from time to time but this isn't a detraction from the other PCs - it's an enhancement of the party as a whole.
As a DM I always use stat rolling and that is non-negotiable. As a player I also prefer it, but I wouldn't walk from a game that required point buy stats.
Lastly, I do find it quite offensive when people try to suggest that the way I prefer my D&D is badwrongfun or that it is unfair to have variations in characters' ability scores. Just because some PCs are a few points better in their check modifiers, doesn't mean they have to rule everything. I wouldn't want to base my fun on how successful another players is, and seeing some variations in mechanical success doesn't make it any less true D&D.
