Really? people are upset about that god awful laugh on a 100% proc that annoys the entire group? It's 100% when you do X. Did you do X? Then it's up. What do you need an annoying sound for?
I thought scatterguns could only be used from behind? Video has him shooting it from the front a couple times. I wish that was how it worked. But maybe there's something other than back blast and shoot first?
