The same day i had sucessfully managed to powerlevel my first character to lvl 11, the banite fighter/rogue celebrated this by travelling to the Anauroch in his Banite Vestment.
On his way he met 2 dire polar bears, "Fear no-one but bane!!", and he was back to lvl 10 again.
Fighting in the market? Hey, that's the only place i went to when i wasn't questing.. There was a lot of fighting there.
