Why Disruptor on Shotgun?

I was one of the people in that match. I think it was you, me, Xan and Ark. As we are obviously only going to run platinum in that lineup of killers, I thought you were joking when you changed the set up to Bronze Rio and equipped an MG set up.

So OFC I equipped a typical platinum set up as I assumed you were going to change back. Then the match started and I realized it really was bronze. And there I was with a L20 SI with a Harrier X and AP IV .. in bronze.

Yeah, you were missile glitching (cool on bronze, not so much on the higher difficulties), however it's not even like my TTK in bronze on that set up was much worse than yours lol

I don't use disruptor ammo on anything. Sits there maxed out at 255 and has as much value to me as explosive rounds and cryo. Disruptor ammo in my opinion should actually just have been what Phasic round are nowadays: a way to negate/remove shieldgate on enemies.

Possibly yes. There is just no use for it compared to AP, Warp, Incendiary or Phasic on the weapons and kits I use. So enlighten me: in what scenario makes DA kill the enemy faster than with the other ammo types I just mentioned?

I never found Tech Bursts particularly useful compared to Fire Explosion or Biotic Boom Boom or... well just shooting and killing the damn enemy instead of fooling around. I guess it's a matter of playstyle which is why I said I don't find DA useful for the weapons and kits I play.

Well I guess by playstyle I mean the combination of kits and weapons I use. That's why I don't want to be misunderstood: I don't necessarily mean that DA sucks or anything, just that I personally have no use for it. Then again I only play like 8-10 kits and don't really enjoy the rest (anymore) and I use a Javelin, Black Widow, Crusader, Claymore or Wraith. I just like to point, shoot and kill and not mess around with fancy combos and such that much. It can be fun at times with a team when powers work well together and I look out for it more (priming or detonating) but usually I have not much intention to explode my own combos and for me personally powers are just the icing on the cake that support the shooting mechanics of the game. Would probably be a completely different story if I was leaning more on powers and combinations than on putting out damage with weapons and going by the "preferrably one shot, one kill" motto. That's what I mean with playstyle in this case.

Widow Juggernaut was one of my earliest sniping setups, using Siege Pulse in much the same way. It was very strong, and the Juggernaut's height is actually an advantage in sniping.

Phase Disruptor.

And I believe you're refering to Incendiary Ammo's 4s cooldown on repriming the same target that Disruptor Ammo doesn't have. Disruptor Ammo is perfectly reliable for priming, prime, and prime again, endless explosions if you have a detonator that can keep up.

When tanking on Gold/Plat, it's most common to get 3 PDs per charge cycle (4 tends to cause shields to be broken by the enemies, which is painful).

(I say "tanking" because a Tech Bursting Slayer can hold off entire spawn-groups once you get a nice rythmn going on some stairs somewhere, the Tech Bursts essentially take the mooks out of the equation, and bosses are not very threatening to a Slayer on Stairs).

If you're playing as a Slayer, TBs are better than FEs vs armor. Not against rippaz tho, because lolswarmerbug 

Claymore to the face or some "ferrofluid, magnetically drawn into the firing chamber and expelled at lethal speeds" (ME Wiki) works even better in my opinion. 

But anyways... thanks to all you guys who gave explanations about the use(fulness) of DA even though I personally have no use for it with the kits I play regularly. 

I use Cryo on my Salarian Engineer.  It makes Incinerate more powerful, makes you a Tech Whore (you now command the powers of Fire, Ice, and Electricity), and most importantly, it causes Melee Puggernauts to drop whatever they are currently grabbing.

It's also useful CC on groups of Cannibals, and unshielded Collector Troopers.  You'll even get a Cryo Explosion if you Incinerate after they hard freeze.

And finally, since it provides Armor Weakening, which doesn't play well with Armor Piercing, you get a free mod slot where your Piercing Mod once was.  On SMGs and ARs, this means a damage barrel instead.  On Shotguns and Sniper Rifles, it means a lighter load, as you'll use the plain barrel instead of the combo barrel.  On Pistols, it means a clip extension or power amplifier.

I better log in sometime and check how many I have left!
