I have to admit, I really don't mind if there are only short hairstyles or pinned-up long hairstyles for Inquisitors. While it might be nice to be able to have long, flowing locks when safely holed up in the Inquisition HQ, it doesn't really make sense for me whilst out adventuring, exploring, and questing. I used to be in law enforcement and long, flowing locks were an officer safety issue. If we had long hair, it had to be pulled back in a tight bun while we were working so that, if we got into an altercation, there wouldn't be much hampering movement or pain if someone managed to grab us by the hair. I think the military probably has similar rules for female soldiers - I know some of the women here do serve, so maybe you can let me know if that's true or not?
I guess this safety consciousness carries over into my RPG characters too. It just doesn't feel practical to me, to design my PCs with long, loose hair. My warden had the big bun on the top of her head hairstyle so it was implied that she had long hair when she wasn't dressed for fighting. I can't remember what style I gave my Hawke...
