There are several legitimate reasons to want the naming conventions you know, BEFORE, maintenance. Naming fairness has nothing to do with it. Literally the ONLY time I was unable to pick a name was because I wanted to play around with the idea of a Roe named River Song, and the name had been taken. If you're sticking to lore style names then the fact we have a first and last name makes the idea of someone stealing a name absurd.
What's going to be unfair is the congestion the people who really a super hyped about it are going to experience as everyone not only scrambles to race change, but name change, AND log in all at the same time. I feel for those changing their mains for that reason. Really I do. I only want to create an alt and get her reasonably ready while the Monk lvl boost is on sale as I'm pretty sure that will end with maint, and I'M getting antsy about it.
So yeah, Square needs to light a fire under the chair of the guy in charge of this. I know it's not exactly a minor thing but c'mon... you've had literal years to develop the lore by now. Sorting out the naming conventions and getting them to us in a timely manner should not be so difficult.
