When we started playing 4e I switched from using point-buy to using stat arrays. This means everyone's starting on an equal footing _and_ min-maxing is minimized.
Of course this leads mostly to cookie-cutter builds, but I'm fine with that. There's still been minor variations (e.g. switching primary & secondary stats).
I definitely like it better than players creating ineffective characters "for the sake of roleplaying". Unless you're playing a pretty untypical D&D game, combat is going to be important, so what's the point of creating a genius, weakling fighter?
It's detrimental to what I consider a fun game of D&D and in the worst case can ruin the game for everyone. It's not even realistic: If you don't have the slightest talent for something, there's no way you'll end up doing it for any appreciable length of time (unless someone else benefits in some way from your incompetence...).
Just to be clear, I'm not trying to get my players to create genius weakling fighters or dumb brute wizards. What I'm looking for is something that doesn't result in the same classes using the exact same stat every time as a dump stat.
So you wouldn't have a weakling fighter, but maybe he would be a bit more charismatic and a little less wise. Or a little more intelligent and slightly less dexterous.
Just something different to the cookie cutter stat builds that show up time and time again.
That, and not have one PC have awesome stats due to rolling well, while another player is Joe slightly above average (in some stats) due to some bad rolls.
