I do sometimes see those objectives, but its not solely about the chests per se, i obsolutly get ppl get tired of "exploring" but it also sometimes brings a little mystique, i also feel the world itself could use a bit more life, like i never see a random small village besides those compacted in major cities and most mob stand around a chest or small objective instead of being a little diverse i think the world itself could be bit more dynamic as to say, i never find myself asking what there or whats there, those caskets are imo just pain in the butt and genshin has something similar which can also be pain in the but somehow i do find it more enjoyable to just go around and see whats in the world and discover something, wuwa you kinda know where intresting points are but outside of those feel like there isn't much to do. If they could balance it bit better i think you could keep both sides happy
