It seems it is likely the real "you", this time. Fake accounts of Blizzard artists have been done in the past, so I am not 100% sure. If you can, I really suggest you consider fighting those fakers officially at your company.
If you're the real deal, then I'll gladly stick around. Even though I have to stick to a simpler manga style to express my ideas (because I am just not that talented XD), I deeply respect the design work made by Blizzard and you in particular. It is a great source of inspiration and learning... even for us who kinda suck.
Anyways, enough ranting about me. Keep up the great work and best of luck for the future.
