Not sure what the community's prespective on this will be but I'd LOVE to see:
1) A barber shop come in. Where you'll be able to change your characters hairstyle (...and maybe looks as well?). I made myself a character and leveled him up to level 20 when I realized I hated the way he looked. Plus when I got vampirism he started looking even more whack
2) This one should be super easy to implement: different backgrounds at character select. As mentioned above my character is a vampire, so he has that whole dark an edgy look, plus the amazing VR gear. Unfortunately if I go to character select the background to my character (who is in AD) is a plain of flowers and rocks with a gentle river. Talk about a kill-vibe. Doesn't feel like I'm about to select the biggest bad-ass at all. Make this acheivement based though; so if you become VR you unlock the "VR background". And if you beat Molag Bal you unlock the "Coldharbour background". Awesome right?
