One of the things that I miss from other games, mostly Aion, was the wider degree of customization with characters. Rift offers a lot of the same features, but we're still very limited in the degree that we can customize. For example the height slider lets us adjust our height, but we can either be tall or slightly less tall.

Plus there is only around 12 hairstyles and some of them look basically the same with slight tweaks.

I guess my suggestion breaks down to this though: Give us a much higher degree of customization with characters so we can make our own unique character, and add in some more hairstyles. Compared to other games I still feel more restricted despite more options.
