It's hardly confirmation that Blizzard is thinking in this direction -- Daxxarri says the discussion is "just for fun" -- but on the official forums CM Daxxarri has responded to a thread about character customization options asking what players would most like to see
Just for fun, if you could pick your top three character customization options, in order of preference, what would they be? For me:
2. More facial hair options for males
3. Racial 'variants' for those who have them
Is this reason to hope we might get more character customization options -- or even more varried racial skinning options
-- in the future? We're not holding our breath based on this thread, certainly, but if more customization is what you're after, hop into the thread to let Blizzard know.
