I dont see why everyone saying rogue is so tough. Im currently leveling a rogue did 1-51 grinding, 51-60 AV (in like 2 days), 61- 63(current) with Mixed EoTs since its call to arms and panyamas fireflys farm. I've never used the default CC, i been using wired's shadowstrike CC and its phenomenal for choosing poisons and pull options and abilities.
I had no problem taking on 3 mobs at lower levels after blade flurry and now at 60+ I can do like 4 or 5 with blade flurry and killing spree no prob.
He does eat a lot after multi mob pulls, but who cares.
