Hi, I just started playing WoW .. so I need some advice.
I just rushed through levels without noticing I wasn't getting decent equipment for my character.
I asked about equipment, and everyone told me "go to isntances", so I searched a bit and realized that I could go to instances since level 10 (Horde btw).

Is it possible to solo an instance? I'd like to play solo until I know more about the game, so ... which class would be fine to solo a low level instance?
What are the Horde low level instances? Thanks!
