Replaying Boss Fights
Currently if one wants to replay a boss fight they have to go back through the whole quest to get to it. I think it would be amazing if after completing a major boss fight (like grandmaster) one had the ability to replay it for 0 rewards. It would be an awesome way to practice and just have fun. I imagine the way it could be implemented is with a special quest containing a number of paths each that one could teleport to a different boss with.
