On topic: In our short lived OW game, one of the players used a plasma cannon and had disastrous luck firing the **** thing. It overheated a half dozen times in 2-3 sessions. RAW, you take damage, or you drop it. So he dropped it every time. His turn following that was always the same: half action to pick it up, half action to brace it. He was not impressed with the thing.
That seems more like an argument for why it should be kept. If you drop a plasma gun to avoid damage there should be negative consequences to that course of action.
Also "a facetious attempt to argue from authority some grognardy position" should be "a facetious attempt to replicate the tone of a grognard arguing from a perceived position of authority". Seriously, if you're going to call so many people on proof reading, at least get the grammar right
