Bobhopekilledme, you can Vanish. You'll get the ability next level, level 22.
I'd have to agree that Rogue wins on SOLO 1v1 PvE, but when you get an add, it REALLY hurts. Paladins are very tough in PvE and can take 3 equal level mobs at once. Hunters do very well for them selves also.
But, since I'm a rogue, I'll tell you how my solo works. I've played with 2 different specs: Heavy Combat and Backstab. The backstabbing rogue must gouge, position, and backstab. Fights tend to be long, but they take very little damage overall. However, when one gets a link, things become very nasty, and one most likely will waste a Vanish, Sprint, or Evasion.
The Heavy Combat rogue, my current build, is much more direct. I stand still wailling Sinister Strike until I unlease a five point Eviseration, which crits for near 500 damage. I don't stealth much as a HC rogue, but I'll open with cheap shot (4 sec stun and +2 combo points).
I also play a Paladin which is level 25. Paladins are PvE gods! They can take elites of an equal level (with downtime). Or 3 equal level mobs at once (with downtime). But, a lack of ranged weapon hurts for pulling. Chain killing is very easy because mana is always regening as long as you haven't cast in the last 5 sec.
