The sidequests were always just shitty MMO-style fetch and 'extermination' quests, but it wasn't a problem because they always went by super fast. You take three steps outside a town, kill the monsters you need and find the items, if you didn't already have them. Once you hit Frontier, though, the pain in my ass level increases dramatically. Suddenly, I need to get items that very rarely spawn, meaning I have to constantly teleport back and forth until it pops.(Fuck you, Empress Beetle) What made it even more tiring was that Frontier is full of quests, that actually require you to go back to the giver after completion, betraying the game's established take on questing. This wouldn't be a problem if Frontier and Makna Forest weren't designed by assholes, with generic Nopon, after generic Nopon crowding every spiraling floor. Plus, the game doesn't let you track sidequests, so you can't just run to the person, nor does it give you the time they pop up in town. Very frustrating to a person that has spent hours upon hours with these quests. Anyway, I thought Frontier was bad, but Alcamoth kinda ups the ante when it comes to confusing design and disappearing quest givers. I'm at the point where I just want to abandoned the dozen or so quests I have left at Alcamoth, I just can't take it anymore. Of course, if I decide to take a break and focus on the story, then those dozen quests will lost forever.
Basically, like Kingdoms of Amalur, you can drive yourself crazy and sick trying to do the hundreds of quests.(Plus, the boss fights become easy as shit because you level up so much)
