Not to mention that people will probably continue to call you by the 'Evastio' nicknames even after you get the name change. Just because you change your screen name, doesn't mean that everyone will suddenly forget that you were once Evastio. And as it has already been pointed out, people will make NEW nicknames for you. You'll not get out of it by changing your screen name.

But yeah, I'd go with the general "Keep Evastio" thing going on here.
