IMO a stealther is the best for rvr, you have a shadowbade and a hunter. The shadowblade is great with their critical strikes and high stealth, while the hunters can be deadly snipers with their bows... It all really comes down to how you want to play, the SB's can take down other chars within a few hits, and can take a few hits too. The hunter has the advantage of range, and can also take down other chars within a few hits.
