It's funny all the posts talking about "cookie cutter" characters with point buy. I haven't seen it.
Here's a sampling of characters:

Human Clr 28 points
Str 14, Dex 10, Con 10, Int 10, Wis 16, Cha 14
Dwarf Ftr/Clr 28 points
Str 16, Dex 14, Con 14, Int 10, Wis 14, Cha 6

There's a fair amount of similarity in the stats. There's certainly a lot of 10s and 14s. However, out of the 15 or so characters, many of who fill quite similar roles, there's plenty of humans and no two sets of stats are identical. I didn't see any cookie cutter characters in the 30 point buy RttToEE campaign I played in either. The closest I've come to seeing nearly identical characters was the first time I played in a 32 point buy game (Living Arcanis).
I showed up with a Val barbarian Str 16, Dex 14, Con 14, Int 12, Wis 12, Cha 10. Another guy showed up with a human barbarian Str 16, Dex 14, Con 14, Int 12, Wis 10, Cha 12. But the characters themselves weren't too similar. He was focussed on reach weapon combat and my character was designed to smash things up with a Tralian hammer (2d8 /x4 exotic weapon in that setting--yeah, I'll admit I'm a bit of a power gamer--but I also had these Mordheim minis with 2 handed hammers that I'd never used

)
If I had to build another front line fighter for that campaign, I probably wouldn't use the same set of stats either.
