As along FF fan, I can say that my first time to finish the game with these two dungeons was round because of the overgeared player and the speedrunners. SE can and should fix this since their whole game is story driven line all other FF's. the final dungeons are 8 man’s party and it should be challenging by making ilev "synic", this should solve the problem by making ever single party member needed to progress. in my personal experience I missed 2 major fights because the other tank was ilev 90 and did not need me. I just want to say for all expert and high level player please remember the thrill and in the early dungeons, I really miss it at the end.!!
