tl;dr: Delete Phantom and risk not being able to make one again?
First off, names matter a lot to me, I'm a bit of an RP nerd (spent 8 years on a RP server in WoW, so names are kinda... OCD to me) even though I obviously won't even be doing any RP in MS (because lol @ maple's "story")
The name my Phantom is currently using, which is also my name in SP, Zaicil, is the name of one of my OC's and one of my old WoW characters, and the name fits the... "style" of Luminous nicely (RP'd as a Balance Druid under the name, for anyone that knows WoW... for people who don't, they switch between using the power of the moon and using the power of the sun, kinda like the light / darkness thing)
Anyway, I hate my Phantom. I'd have no problem deleting it, except... well, I might want to get the link skill someday, and I dunno if they'll be opening up character creation for Phantoms again anytime soon.
And I REALLY wanna use the name for my Luminous, because it fits the character perfectly. Aaand I don't wanna think of a new name.
