I found an easy way to build up weapons skills today in UC (even unarmed), and since it's in a control town its not likely you'll get killed or hurt by the lvl 62 scourge that runs in to UC. You just have to listen to when one of the merhcnats or bank tellers tells you. Simply run to the mob and attack with you desired weapon.
SInce my toon is only lvl 23 and a priest, I was able to lcvel my staves skill about 10 points before the guards finished him off.
Granted it's not a great explot, but I'm sure it's something Blizz did not intend on having this guy be a temporary training dummy.
