Starting from May 15th, the official will select from the players who apply for the nostalgic test (the registration is not necessarily invited), the selected players will be invited to participate in the small closed beta test, and the players participating in the test need to be in Battle. There are still game days or game hours in the net account to participate.
The mmoah website also prepares a large number of WOW Classic Gold for players to play more fun, and there are more free game guides for players to refer to.
