WoW Classic PvP Honor Rank Not Updating

For an increase in the Honor Rank each week, players must meet the requirements in Contribution Points (CP), plus have a minimum of 15 honorable kills that week. If a player meets one requirement but not the other they will not increase in rank. Ranks should still be updated with the weekly reset.  

Important - Character Transfers
Your PvP rank will transfer with your character but any kills you earned on your source realm between the weekly reset and the time your transfer comes into effect, and any honor from those kills, will NOT transfer with you. If you want to keep all your PvP data from the previous week, we recommend you transfer 24 hours after the weekly reset., once the calculation has finished and your rank updated.
