Was able to get Ell as my legacy name on The Harbinger server. YESSS!!!!! *fist pump*
On most of my characters I just display it as part of the name, e.g. Vrahn Ell
I too am very interested in seeing what legacy levels do for you in release 1.2. I've already got 6 characters on my account though so if some of the benefits are new character creation options then I'll be somewhat limited.
