I actually don't mind how the changes to talents and skill trees are structured: the old way was just getting too bloated and many talents within trees were "mandatory" to begin with. I do still have to try and figure out how all my stuff works all over again (this would be the fourth time), which will take more time for all my characters than I have available with a 7-day pass and extremely limited free time for doing so. I may yet buy a month's playing time, but certainly not the expansion. It will be fun to PK all the monks as they try to level... expansions are the only time you see world pvp anymore with all the end-game content instanced and teleporting from everywhere in the world. My level 20 druid in heirloom gear will have a blast!
