Hi, I already asked on the in game help section but i'm having problem to realize my wish.

I wanna change my toon name in Obi-1.

The answer i received in game is that there are rename tokens on store, but i'm afraid that will not work.
Not only for the -1 thing but also because i already have a free rename token,
and when i insert /changename Obi-1
it says (Error): There was an error while renaming. The name you have selected is banned.

I appreciate any help in achieving my wish, ty
