I’m gonna say no if things remained as they are currently. Scellerata, Trixxia, I’ve had those names for over a decade. Hell, I was the first Scellerata to ever exist on the armory. I was the first Toots. The first Risovino. I spend a lot of time thinking of names, looking up synonyms, mythology, scientific terms, translators, etc… I lost Celeste when I moved from Dalaran to Hyjal and that damn near killed me. It still eats at me that I had to resort to using an accent to get a semblance of that name back.
Now, the only way I’d support potentially losing my names is if WoW was given the Guild Wars/Guild Wars 2 treatment and required us to have first and last names for our characters. That would open up a TON of options and then suddenly it wouldn’t matter if we had two Bob’s or thirty due to all the possibilities for last names.
