Which brings me to my point. They have a +3 ECL, although I thought their powers maybe seemed more appropriate for +2; not sure how much Flying is worth. But they have one trait that seems very hard to address with a fixed racial ECL - ALL Fairies have d4 hit dice, regardless of class. For a sorcerer or wizard, this is no penalty at all, but for a fighter or barbarian? Please. So I could see this race having a +3 ECL when the PC is a d4 or d6 class, but maybe a +2 ECL for d8+ classes? I guess this situation exists with all standard PC races, and will be even more noticeable for some monster races, but this seemed really extreme.
