I'm not sure... I had the Inquisitor set with that nice speed boost, but then I managed to lock on a nanoskin armor which won't come off and is blocking my technician diamond this run(so is a complete lack of chainsaws - how do I get 3x DS and not a single chainsaw?), so I don't think I have the movespeed to make a melee clear work. Currently I'm sitting back and blowing people away from ridiculous ranges, especially if I get light amp or tracking computer - if I had to close all that distance, I think I'd take more damage then I could sustain.
Even if I could one-shot anything with DS, that's not a huge improvement over my current weapon, and it exposes me to far more damage... unless DS has abilities I'm entirely unaware of. Not something I'm really willing to risk this run, I think - maybe when I go back with Scavenger to finish off my assembly collection, I'll give it a try if I find it again.
