Personally I support the change, only because Blizzard already knocked a hole in the wall, when they allowed selective PvE--->PvP transfers a while back to correct some glaring Faction imbalances on some PvP Servers. To me the policy should be all or nothing, either PvE--->PvP is never allowed - ever - or it's open slather.

I was hugely annoyed when the opened up Aman'Thul (PvE) to Thurassian (PvP) (both Oceanic) recently, as I had been levelled a 5-box team on Thur, but was in no way at all going to put with being ganked by people who hadn't had to go through the PvP levelling process.

Still, being mostly focused on PvE, I don't intend on transferring. I am hoping the Lake Wintersgrasp works out well in WotLK, because then we'll have a useful whole-zone to go to when we do want to PvP, and if it does work out that way, I expect to have the best of both worlds. Zones to farm, instance etc when I want to PvE, and somewhere to go when I want to PvP that will be an auto-flag territory.
