I'm a casual WoW player too, so I don't really know what the whole fuss is about with MMOs. Like everything in life, it's all about moderation. Heck, it took me a whole month just to get from 44 to 45.
Dang rogues, I hate them and never help them (unless they are in my group then I'd consider helping them).
That's just because my first encounter with one in PvE, I get ninja looted. Then I go PvP and I pretty much get owned. Then again, I did roll druid... skilled in many areas but a master of none.
You've got a nice character, but I'd get more joy in leveling my own rogue if I did make another toon.
