Your PvP activities this week will count toward your rank in both Classic Era as well as the Burning Crusade Classic title system (which allows you to display the highest rank you achieved in WoW Classic).
However, we have to initialize our final Honor calculations before we take other steps that will culminate in the snapshot of all characters during maintenance, so we will end the PvP week up to a day early. In this region, we will end the PvP week at:
7:00 a.m. PDT (10:00 a.m. EDT) on Monday, May 17
- This is 22:00 AWST on Monday, May 17
- This is 12:01 a.m. AEST on Tuesday, May 18
- This is 2:00 a.m. NZST on Tuesday, May 18
From that time until maintenance begins, PvP activities will not count toward rank.
Good luck out there!
