One thing on shields, it not based on race but on element of shield, I had a hive knight with an arc shield, and a shank with solar shield Blue= arc Orangy/ yellow = solar Guessing : purple= void Good job I notice something about impact too I also think that impact can have a stunning effect because the difference between to of my auto rifles was on had more impact but less rate of fire, and the gun with high impact seemed to stagger the enemies,,just like the sniper and hand cannon dude
