Chainsaw's Instant Kill should be removed

[Issaella]

You forgot Mch LB ;p
Wildfire + LB combo is about 48k damage.
Mch need something else than chainsaw.

Yeah, if you use a time machine maybe?

I was grinding out my 10 wins for the pony on my alt this week and while I don't have the exact numbers, Spite now hits for about 30% of a melee DPS's health bar (used to be > 50%). For a tank it's even less. Reassemble + Drill or AA maybe hit for 25%. And Wildfire now hits for 20% if you get all your hits in. So lets say you were able to chain all that together: maxed Wildfire into Reassemble+AA, then followed by Spite. That's still not enough to finish off melee DPS on your own, let alone a tank. Now you have blown all your cooldowns, at which point they can pick you apart at their leisure.

As others have said pretty much every melee DPS can do more damage in the same number of button presses. And they have defensives and movement abilities that MCH lack entirely. Buff the insta-kill on Saw based on distance. Make melee DPS at least think about diving MCH for a free kill instead of having zero risk.

Wouldn't this better be a reason to convert some of Chainsaw's potency (literal and/or what's afforded by the rare, random instakill) towards making it immune to passive DR, or at least otherwise evening out its damage to melee and tanks?

Bolded for emphasis.

That would require thought and nuance. The PvP balance team appears only capable of blanket across-the-board nerfs/buffs. Like I've said previously the balance team consists of a monkey banging on a keyboard with a coconut. You can't expect thought-out indiv buffs and nerfs.
