As a MCH player I have mixed feelings on this.

Air anchor and drill are either side of chainsaw making eyes at my analysis, but IF the chainsaw procs death it’s far more worth it than either of them, if not, then I’d rather have used it on the other two for the direct damage increase.

I like the death effect, but the low chance makes it a meme at best. In one of my first matches of frontlines since the rework I fired it into a crowd and it killed 4 people, but I have yet to replicate that and I doubt it was as funny for the other team as it was for me.

It would be nice if it had more specific conditions, for example 100% death on targets within melee range and the chance decreases the further away you are down to 3% at max range. It would give MCH a more reasonable incentive to get into melee range than bioblaster does. Or maybe 100% death on targets afflicted with something like aether mortar or wildfire so you could at least know you’ll get one person with it.
