After a long day of trying to clear prior content it's obvious that players are simply gearing a class with the abundant myth tombs and then queing for fights without practical knowledge.
being addressed by adding the echo boost and adding gear even still ff14 requires a level of skill and steep learning curve per group.
I think it would behove all players by
(a couple of months prior to new content)
Adding a simulation of the mechanics expected of your class for the extreme fights. Players MUST complete the simulation WEEKLY to unlock the fights for duty finder and party finder.
this will re-teach classes people with to pick back up, and create overall smoother runs/less headache for everyone involved.
+after a break or leveling other classes when new content comes out not everyone wishes to re-do and help others clear, for HOURS.
basically this all comes down to ... "give a man a fish feed him for a day, teach a man to fish feed him for life"
