That does help, but unfortunately, Character Transfers will not transfer your kills from your source realm, because its not fair to the players on your destination realm for you to bring in kills from a different environment into that week’s standings. The kills are still recorded, they just don’t count on your destination server. This was true historically as well, and is not a bug.
The character transfer will bring over your current rank, and progress toward the next rank (the results of each weekly calculation), just not the kills that you’ve achieved so far during that week. The best time to start a transfer, if you’re concerned about PvP ranks is immediately after you get your new rank.
We’re continuing to work on improvements so you’ll see the new rank reflected in game as soon as possible after the weekly reset.
