I'm still in chapter 1 and one thing pissing me off is the way dungeons are handled. Like you enter the mine, you fight some stupid level 7 mobs and of course you think the dungeon can be done, of course the boss will be harder but it seems manageable. But no, you reach it and bam, your whole party dies in one hit because the boss is level 52 or something like that, doing 9999 of damage. This applies to some hunts too: you see the suggested level and the enemy you need to face, if an enemy is too strong there's the red sign, but often there isn't. Like those dark blob, I know from other FF they should be weak to magic, wasted all my spells on them, did almost nothing. Yeah, the damage were bigger compared to physical attacks, but still the fight, since I was level 9 and they were level 14, was long and tedious, because eventually spells will end.
Dunno, the whole openworld reminds me of MGSV, there's not so much to do, if not killing monsters and grabbing pointless items or ingredients. Exploration isn't rewarded because often it ends with your death and a game-over screen, so what you did is useless since you need to re-do it.
