As much as I like Plasma weaponry in Odyssey all 3 guns are hardly useful. Like I get it they dont have damge drawbacks like laser or kinetic but its almost impossible to hit moving targets with those weapons. It doesnt need to be much faster but at least fast enough so you can hit medium range targets with the Automatic and for the Sniper enough to hit long range targets.
Oh and I am fairly sure a gun with which it is impossible to hit moving targets would never enter service anywhere not even in a fictious game universe
