^^^ Not sure how to explain it, but the grind feels imbalanced to me. My adventurer rank is going up faster than my characters and gear can level up, leaving me feeling underpowered. Some of the stuff I need only drops on certain days and it's just a pain to keep track of all of it. And I never ever ever have enough XP scroll things to level my characters properly.
Also, Inazuma is such a dark and gloomy land in most places that I suspect it's affecting my mood, making me feel depressed and unwilling to play. :/
^yeah, not unlocking your AR stages willy-nilly is a must. Farming is chore enough without enemies outleveling your chars and gears. I made that mistake once and ended up largely quitting the game for a few months in frustration.
Bonus points if a char uses same annoying enemy drops for Ascensions and skill upgrades... *stares accusingly at Kokomi*
