Barrier champions are broken after Renegades DLC out. They can only be stunned by certain exotic weapons with an anti-barrier perk. As example - Wish Ender bow. Unstable ammunition for void weapon, the artifact bonus for regular handgun and sniper rifles do not work like in the previous DLC. Sometimes almost the entire weapon magazine empties without any effect. This makes most of the regular weapons useless and all your efforts to make builds more diverse become equally useless.
