I’m enjoying it a lot. There is so much to do. The PvP is fun, even for a lowbie level 21 like me. I have a lot to learn about PvP objectives though. I have really enjoyed trying out the different weapons and learning new traits. I’ve even enjoyed healing, something I really didn’t enjoy in WoW.
I agree with Nawat that it’s better to start with everyone else who is also learning so you’re not a stand out noob.
