Reserving names for classic

[Perl-anetheron (Perl)]

That might be a better question for the Classic forums to be honest.

That said, I managed to find this quote over there:

Reserve Your Name in WoW Classic on August 12 at 3:00 p.m. PDT

If you delete a character during the name reservation period, the name of the deleted character will be available for others to use right away. This is how it works in the live game as well. Only characters listed on the character creation screen will have their names reserved and you won’t be able to hold additional names by deleting characters.
