As Wgticon has said... cannot be done. I have tried.
I want the 0014 at the end of my name deleted and just have Mantis.
There is mantis in the system at the moment... joined in 2008 and hasn't played any ranked rounds.... not one, if any game at all....boooo....lol
I think Wgt should get rid of him/her so I can take the Mantis as my profile name.... I still want all my stats and what not kept too....lol.
