Yeah, pretty much anyone who wants to be a Wizard chooses Eladrin as their race. It's the only one that lets you boost your Int, except for Human. But Human isn't as good as they make it out to be... Only one stat gets a bonus, you get an extra at-will power (but you can still only do one thing per round!), you get a bonus to all three saving throws. But Eladrin gets a bonus to both Int and Dex, gets that wicked per-encounter Fey Step teleport, and still gets a bonus to one of their saves.
Honestly, if one was trying to make the best Wizard, one would always pick Eladrin.
Me, I made a Halfling Paladin, not at all the best race for the class. But I wanted to be different.
