Your really have to take it as red that rommath is hiding in the middle of the city
Now obviously cause of the way dalaran is designed he does stick out like a sore thumb but story wise he is keeping his head down in the middle of the city and what with all the commotion jaina didnt see him
Also has any one attacked landolock during the dalaran fight i did and he attacked me with all his dailie bosses which i thought was amusing
Also regarding why the eagles couldnt take the ring to mordor wouldnt the nazgul who ride felbeasts seen them and attacked them before they got anywhere near Mount Doom it wouldnt have been worth the risk
