I had to add an extra E to my name just to be able to play on Ygrassil ><
I have a level 4 character on the other US West server, but have not played him, would like the option to have my name be the same on each server (unless taken by another player, then it makes sense to not allow it).
I believe they want to play on both USE and USW servers but use the same name. I dont think its a big deal though a lot of games have it so you cant use the same name. I personally suggest just putting something at the end like Smiles USE or Smiles 2 or like you said change a portion of the name.
