1. why do you have to be so rude, 2. I've beaten the whole game, base game, secret levels, DLC, and everything. 3. I enjoyed the game a lot, definitely one of my favorite games ever.
I'm just saying that the bosses aren't that exciting to fight, because most of them don't have that many attack patterns, it just feels like this in-between their attacks is all I'm saying
you're probably almost 100% spot on about Shrines and Towers, Guardians probably went back into the five giant pillars that surrounded Hyrule castle, which is where they came from, not the observatory. side point, the Towers purpose was apparently to detect the arrival of Calamity Ganon, and a lot of good they did.
