At some point in Episode 5 many fields (forest, volcano, etc) got an Xtremely Hard difficulty. In GL, we just kinda skipped over this in favor of Risk Exploration. That's nice and all, but Risk Explorations are unfortunately not in sync with the dailies and frankly, are too time consuming to solo.
Xtremely Hard is a fine middle ground that lets solos or friends join up and do dailies and actually be entertained. One shotting Super Hard enemies for basically no reward is just tedium for tedium's sake and there's no reason to force people to do that when JP had already introduced an alternative.
But... it's also supposed to be in the game so I shouldn't have to write a dissertation to justify this. Just please put them back. Thanks.
