RTTS boss challenges

[Sprague1135_PSN]

Do we know if there is a way to get better equipment from boss battles, such as if I play on a higher difficulty does it give a chance at gold or better equipment?

I was playing Simulation and on all-star and had a boss battle. I got diamond gear in my reward pack. Probably based on chance.

The quality of the reward matches the level of difficulty of your settings I would assume.
