I don't understand name changes. It just erases the impression you've already made in peoples minds to remember you. Its like starting over in a bad way.
I had the same mindset for a long time, but an alias is an alias. Most people on XBL will still call me Kuroda, or Matt. I wanted a name change for the sake of the meaning, mainly. Rorak Kuroda didn't mean anything to me, this name actually has meaning that pertains to my mind/personality/artistic vision/whatever.
DAMMIT RORAK that name sucks even more balls. leave and dont come back until it's less than 4 syllables
