ahhh okkk ARR means quests for A Realm Reborn I believe. As I said above I am on a level 42 MSQ quest right now. I believe that is high enough that I should be able to talk to the UL'dah citizen. If I am unable to find any other reason why his icon is red - and from the posts so far to my original one it doesn't look like I am, then I will continue to concentrate on the MSQ quests at least until I have reached level 50 before giving up altogether on becoming a Samurai.
