I get how it works but having to rekill the bosses is pretty dumb. It should at least save that. I can't think of any other game, open world or linear, that you have to kill the boss every time you go through an area you've been to before. AKA like every game ever from Metroid to Skyrim. I'll give it another shot with an open mind but I can see that getting really annoying.
I would quit playing Borderlands forever if I couldn't re-fight the Bosses!! You obviously just don't get how this game works
