Am I addicted? Maybe a little. In the last 7-9 days I have managed to take my mage from level 16 to level 21 (half way to 22). Some of the quests are harder playing solo, but I have managed to hook up with some helpful folks. I have also ran into some of the unhelpful sorts.; typical juvenile behavior.
In the last few days I had a couple of fun moments. Fist, I sold some swiftthistle on the auction house for 4.75 gold. I have no idea what it is used for, so I have no idea why it is so in demand, but with 34 gold in my pocket, I feel rich.
Another fun moment was watching a Tauren enter Dun Algaz as I was traveling to the Wetlands (Menethil Harbor). I decided to follow this nut to see what would happen; I was kind of curious to see if this was the type of player that triggers all the ‘local defense under attack’ messages. I think Tauren got tired of a Gnome following him, so he started intentionally drawing orc towards me by firing arrows in their direction. After I decimated a couple of orcs, the Tauren grew tired of the game, and left. Good stuff.
Tonight I decided to visit the Elves (or at least I thought I was going to visit the Elves), so I took a boat from Menethil Harbor to Auberdine. After a couple of quests and a jaunt in a Cliffspring River cave that resulted in my death and ultimately some satisfying strategy to escape and complete the quest, I started traveling. I finally called it a night in the eastern area of Ashenvale after I kept seeing 27+ level nasty things. I just looked at a map and realized that I should have taken another boat to see the Elves and I was fairly close to Orgimmar (I assume life would have been hell if I made it that far).
All in all, I am having a great time with the same seeing what is next. I think I need to find a guild that has a lot of players around my level, because I am not sure how much harder the game gets without having someone around to help.
