They're around. My current party is doing Way of the Wicked, and we have two human members, both rogues (one is a animal handler and the other a trap specialist, and possibly a human alchemist. The other three members are a tibbit ranger(Dragon Compendium: essentially halfing were housecats) with the skirmisher archetype, a tiefling priest of Asmodeus with a birthmark on his back that acts as a holy symbol with the harm good/heal evil turn archetype (the name escapes me), and an auran diviner going into cyphermage. The last group I ran for had almost exclusively human, half-elf, etc races. There is nothing wrong with not playing the classics to the norm. Exotic characters work in a lot of games, in others they don't. Much of it really depends on a good DM working in the back stories for PCs that fit.
