Just fyi: you will still be counted among the ranks of your “home” server (pre-transfer) if you transfer during a tourney. Aka: you get the reward that your original server gets. Don’t make your choice just based on this tournament!
You didn’t read the blog post.
“Your world association will be based on your participation throughout the tournament. If you play on multiple worlds during the tournament, the world you represented the most will be the one with which you are associated. We are adding a new Battle Historian NPC to all the WvW maps who will tell you which world you are associated with.”
I misread it. Thank you for helping, mr. Copypasta.
