I <3 the RvR! Since the preview weekend, Ive played most of the classes and all of the archetypes. My favorite has to be the tank, specifically the Black Orc/Swordmaster. Im just not a fan of the twisting auras. Mass survivability and decent damage to boot!
During the Preview Weekend, I played on Cracker drak? Im not sure, but it reminded me of Cracker Jacks, thus being the best server on the list! For the Open Beta Ive been playing on Helborg and Helbrass. Mainly Order, since I had my Destruction fix earlier. Destruction just has more flavor IMO. They outnumber the Order a fair bit on the servers Ive been playing on. Makes open world RvR a bit funky, but I always just ran away due to my ranged awesomeness that was a Shadow Warrior...
Heres a list of servers and when theyll be up.

Sylvania gets my vote, light bulbs FTW?! =P
For retail, Im looking at maining a Black Orc or Zealot. Next up would be a Squig Herder or Marauder. Ive found the non caster dps to be very consistent but not very threatening. One on one you can kite just about everything.
