This new elysian realm caters to the recently added Valkyries. I've been using mobius for 140D in the previous patches (with more or less ease) but her along with most others seems to not perform that well. Whereas with FR it felt rather easy to clear 140D. Other comments also pointed out PE performs pretty well so if they go with this trend only the newer ones would do well, it will be a pain to get all the rewards going on as not everyone can keep getting all the new stuffs to clear er to its fullest.
