Guild Wars 2

I suggest that users are allowed to change their display name.
With regards to the issue that it would be difficult for GW2 to track players, I suggest that GW2 give each player a unique ID which is irreplaceable. Using username as unique ID is a bad practice in my opinion.

Ex:
ID: 001293
Display Name: BigDy.2491

GW2 can also charge users if they want to change their Display Name. Some games already did this.

What do you guys think?

I’m up to that.
Some of my friends would like that option a lot.
I personally would also.
