I partially agree, we had this discussion in another thread, but i can’t find it for some reason. While yes, this is story driven, i always loved farming bosses for their weapons for example in BL2. There it also made no sense story wise to encounter a boss again, but u could just go back to the boss arena and fight it again until u got the desired legendary.
Sure u can do that by just creating a new realm but having 179 realms just to get the boss drop u want seems a bit excessive. If the story aspect should be “maintained” there still could be a bounty where u go back to the boss arena and maybe there is a new abomination there with the same loot table or something.
I can understand the desire to farm bosses or enemies for their rare drops.
Edit: i found it: Replay story bosses
