Ok well I've been here for a while but havnet found anything worth posting until now.
This bug is actually quite simple.
What you will need is a friend who is a priest.
Say you want to get rep with SW, simply have the priest mind control a questgiver, and you can do the quest.
I did the cloth quest to turn in wool cloth and got to honored with SW.
The city will still attack you though unless its a vendor if you open the vendors shop it will stop.
annnnd yeah
thats about it
also this is cool if you want to get like the opposite factions PvP gear, you can either get rep with SW or just mind control the vendor
