Few of us did a couple of the instances in Annuminas, the city in Evendim occupied by Angmarim.
Just wanted to suggest to so them if you didnt try yet.
I was really surprised about how nice the instances are, well designed and beautiful to see. Also they are probably a good challenge at level 50.
Feeling a bit sorry myself i didnt try them earlier. Though it doesnt seem there is any good loot besides the barter items, the look and feel
of the areas alone is well worth exploring them.
I still got 2 characters at low 50s (Loremaster/Captain) and would happily join if anyone ever decides to do it with characters in that level range.
