In addition to the ability to redo hair as many times as you wish (suggested elsewhere), I'd like to propose a second chance to get your favorite character to look/sound just like you want once you've put up with the initial hazing that is Tortage.
While all of my characters look right, I apparently flubbed the voice on one of them.

This is an extremely minor thing, but it's like that annoying mosquito you hear while trying to sleep but can never seem to find.
I'm sure others who start off with a character in mind end up with a character going in another direction RP-wise wouldn't mind such a feature. Since you can do it once, it
shouldn't be too difficult to allow it twice. ("Shouldn't be" and "isn't" aren't always in agreement.) Of course you can't change class which means you can't change race. I see no problem with changing gender, but I'm not partial to changing the name for the same reason as stated next.
The reason for the one extra chance at your character appearance instead of as many times as you would like is I see this as a way of trying to confuse others of who you really are if abused. Surely once your character is set after playing for a while (hence the restriction of changing only
after The End Battle), you wouldn't need to do it again. No?
As I mentioned, this is not to replace the suggestion of redoing hairstyles as often as you want (or as often as your character can afford).
Despite my aversion to the name change, I'd go with popular opinion on it. I'm neither for nor against an in-game price tag to making the one-extra-time change proposed here.
What do you think? Viable? Worth it? Just re-roll (and possibly end up with yet another character going in still another direction)?
(Holy crap! I can write long posts!)
