Also . . . we will not be able to do our Level 58 class quests until reaching Level 58 - which will be after Moria and Lothlorien. These Level 58 class quests will require returning to the six Moria instances. If we accept the Enedwdaith Option, it means "telling stories" for a few weeks when we get to Lhanuch (in the middle of Enedwaith) as we go through the Moria instances and complete our class quests. They have a couple of nice huts we can muster in at this time. And we do not each have to return to all of the instances. We simply need to get the correct classes through their correct instances - Grand Stairs for hunters, Skumfil for minstrels, etc. (*Imagines a pack of 5 hunters plus 1 minstrel going through the Grand Stair*)
And, if we go with this option, there is the question of whether we go to Mirkwood immediately upon reaching Level 60, or staying in Enedwaith a while longer to complete its Level 65 quests - including the fellowship region of Thror's Coomb before returning to Mirkwood at Level 60.
My vote is to go to Enedwaith at Level 55, complete the region (stopping at Lhanuch to spend a month completing class quests), and return for the invasion of Mirkwood when done with the region, still at Level 60.
But, then, I don't want folks to be running away in horror and disgust at the thought of a 4-month diversion into Enedwaith.
