Instances ... the thing is here is i'm only in control of 2 toons so i can't "solo" instances.
If i need to group up, then they will expect my priest to heal. healing a group while controlling my lock to do damage is a bit too much for me.
Especially when mobs are starting to run around and my lock no longer faces them, positioning can become a nasty issue.
So i'm gonna stick to questing, leaving out the loot x of item quests.
Thanks for your advice.
