Tis far too late now, The Legendary peak was SoA and little bit of MoM. SoM is finished , open the door to overrated ROI which came in less than 3 months. Siege of Mirkwood was re-added on June 12, RoI today, September 6.

Moria came somewhere on Mid March 12-15 ,I cannot recall. Only Shadows of Angmar have had a proper and promised 4 months+ timeline. Legendary servers were opened on November 8-9 2018.

They are reducing the time which was a terrible decision , even dumber move because Siege of Mirkwood had plenty to offer with 10 instances , 2 full classic raids. Moria was a Queen of instances and it lasted only 3 months with 3 raids even. Nothing makes sense anymore.

Forget about Legendary servers, Twas one enormous failure with sadly decent potential , It milked only money to SSG with required VIP. In theory everything one could do on legendary can already be done on Regular with Stone. The only difference is few extra titles. Content,skills,classes,store,g ame-play,story, its all the same.

After Isengard except massive decline in point of near extinction unless they do some miracle to keep players interested,but changes are slim.
