Write.. what exactly don't you like about the races you play that you wish blizzard would address?
For me:
1. Cloaks on blood/void elf females to squeeze in the centre like they do on night/nightb elven female models
2. Night elf males have a no beard option with eyebrows
3. At least 1 good looking nightborne male face, no scowl, no wrinkles
4. Blood elf male run needs to be adjusted
5. Night elf male robes need the leg portion looks weird. Probably have the legs further part when in robe items.
I don't think these are too much to ask.. I'm sure you guys have more things.
