This may just be a one-time bug, but if it works, HEY!
I found this when I played on the test-realm (no gamecard atm) PvPing at the arena of Stranglethorn Vale. Here is what happened:
I died at the entrance (not the entrance to the ring, but to the whole arena), released spirit and asked a shaman to res me, but when I did that, I regreted and said that I was gonna log out. I clicked exit and the dialogue that says how much time there is left until exit came up (this might work with the normal logout too, but the dialogue MUST come up). The shaman still tried to res me, and when it was like 10 seconds to go, the res-dialogue came up. I clicked it and when I came to the arena, I was 5 seconds from exiting. Exited as normal, but when I got back the next day, all my talent-points were gone wo.Ot.
What you can do:
1. Go to the arena (might work with ANY place, but just to be sure).
2. Group with a resser.
3. Die OUTSIDE the ring.
4. Release spirit.
5. Click "Exit" or "Logout" and hope that the dialogue comes up.
6. If it does, ask the resser to start ressing you.
7. Get the ressing dialogue, but don't accept until the timer is below 10 seconds.
8. Accept.
9. Just stand in the same position until game quits or logouts.
10. Wait a while and log back :)
If it works, you can now respend your talents :)
If you don't get the dialogue to come up, wait until trying again.
I really hope this works in other places except the arena, so that you can die near a main-city and get the newer ranks of the talent-spells.
