Hi everyone!
Long story short is that display names weren’t designed in a way that allows them to be changed without causing a potential (and significant) batch of problems on the account so we (support) only do them when we reeeeally need to.
Michael, I promise you that if the programmers were convinced to modify the code to allow flexibility with the display name, ANet would make 1000X in profit the cost of that programmer’s time from selling display name changes.
Your company is walking away from some serious profit here.
