I'm avoiding any type of grinding whatsoever, not doing any of the op weapon exploits, not touching trial mode, and playing fights at 2x speed but the game is super easy. Constantly feel overleveled. Ashe 1 shots packs of mobs with mid tier aoe black magic and Basch is an unstoppable killing machine. Thinking of not doing hunts as I unlock them, but I don't want to have to come back later and do a bunch of no challenge hunts all over the place. Do I need to do any hunts in particular to unlock certain endgame hunts/quests/esper fights?
You just need to complete them all. You can go to optional area which is where the bulk of my challenge came from. Like clearing a zone full of lvl 50-60 enemies when I was level 32'ish. Mad XP so my level sky rocketed but like any Final Fantasy the vast majority of the game is super easy. Trial mode is quite challenging and optional content is as well.
