Hrmmm... not too terribly exciting, but last night I had quite the experience with a level ?? rogue. I'm a 44 mage going around minding my own business killing mobs. However, the rogue was killing the same mobs for whatever reason. He saps me; I ice block because I don't feel like standing around for 40 seconds. He cheap shots me, so I blink. At this point I'm getting tired of him, so I decide to make something over it. I figured I stood no chance as I was at half mana, but whatever.
I hit him with a few frost bolts, freeze him, the standard stuff. When he resists my magic, he gets a few hits in, but I manage to always stay alive. For about five minutes we fight, finally, after I had exhausted my mana (after half and evocation and mana jade) and he had used first aid and a potion, he kills me.
I walk back to my corpse, rez, and decide to fight again. I hit him with frost bolt and a bunch more ?? horde roll up. I decide it's time for me to go, so I begin the run to Gadgetzan. After a few strategic frost novas and a few blinks, I break away from everyone except the rogue. He follows me into Gadgetzan and decides to continue the fight. He attacks, and is immediately killed by the bruisers. He rezes, but he decides to do the same thing and dies... again.
At this point he gives up and heads back out. I need to finish the quest, so I head back out there after I buff myself and get full mana. I start the fight once again. This time, however, I get the first strike in. Even though he resisted quite a few of my spells, he stood no chance. After he popped a potion, it took a frostbolt, CoC, and a fire blast and he was dead. He didn't bother me after that.
