I completely agree that point buy is a better method in general. I guess because there are the two sides to it they should probably write it expecting large groups to use either point buy or dice rolling.
I mean, that's how it was in most fantasy. In D&D it's really fairly annoying because elves are frequently fluffed as snobby, pretentious jerks. If they really want them to be better than humans, they shouldn't try to write them as a LA+0 race.I REALLY hope they drop the "Elves are Just Better" garbage from the standard fluff. It's cliche, insulting, vaguely racist, and adds absolutely nothing to the game. Backing that mary-sue stereotype up with mechanics... would be the absolute worst possible mistake they could make with Elves.
