Should you have the proper level (that is 65), there is a way for your character to change faction.
Make your way to the Blade's edge mountains. In the northermost region of the area, Fel Corrupters will drop an item called Damaged Mask.
This item will begin a questline, which will give you the item FELSWORN GAS MASK. Once you equip this item, your reputation with most npcs will become "yellow", and you will be able to use the portals of the opposing faction in Shattrat.
Log out with the item equipped, then back in. Refresh the online list: YOU'RE WITH THE OPPOSING FACTION!
Notes:
Technicalities:
-This has been tested with a human paladin
-My server is running Ascent 4.3
Shortcomings:
-You are able to party-up with the opposing faction but not able to TALK to them (use SKYPE or Teamspeak?)
-Your reputation with them is still hostile, so NPCs will still attack you.
Again, First try. If this is a repost, I apologize.
