First off, I know that when you faction change, quests are reset and you lose all credit from those quests.
I've already faction changed once on a character and went through the whole Argent Tournament a second time for the title. Now I'm wondering if I faction change back to my original faction, will I lose the title again or because I've completed it on the original faction already, will I keep it? Or does the quests reseting just mess it all up?
