I still have just basic WoW E3, but once I get comfortable and things built up I intend to upgrade to BC and then LK. It is funny to see a DK however come through Orgrimmar...the guards throw things at them and spit on them LOL! Yes, 05 the game is really that addicting! There is so much to do and so many ways to make your each character unique that you don't run out of things to do. Add to that the many different classes and races on 2 different sides and you find yourself having to stop and think which toon do you want to play and what do you feel like doing. You can set yourself a goal and before you know it 2 hours have passed like nothing and you have found something else to do next. There is even a choice to play on servers where you are or are not flagged by default for PvP, and you can change the server you play on without losing characters and build up new ones on a different server. I have characters on a Player versus Player server and characters on a Player versus Environment server and can switch freely between the two. Try the 10 day trial out and give it a test run, it is a free account and does not require a credit card or anything to use so you can play for 10 days.
