I've spent some time with each of my three characters in pvp, and have enjoyed it, even though none of the characters I play have progressed beyond level 36. I do spend most of my time with crafting/gathering, solo questing. But I wouldn't mind being in the keeps doing my crafting, and as the battle returned to the keep, I could again climb up on the walls and set up an artillery station once again. Loads of fun for me. Guild vendors, crafting stations, a bank... and if the keep changes hands, my little crafter could move along to a different keep and continue his work. Some players might like to change gear up a bit during a battle as well.
