Why are people so reluctant to RULES OF NATURE anyways, it doesn't even do that much damage.
Weren't you the guy that modded swords to be overpowered?
What does that have to do with the explosive damage from destroyed Sectopods? That sucker was on two health, even a pistol would have killed it.
But yeah, sort of. I gave the second and third one perfect accuracy and slightly higher crit chance, and gave the third one a bit of armor shred. Basically enough that you can feasibly use them in Legend difficulty against weaker enemies. Buuut then I also tweaked the pod spawn pools so that there's more of everything and they're guaranteed to spawn nastier things, up to and including
Psi Witches.
It's a nice medium ground. They still don't compare to vanilla shotguns in terms of raw damage (I'm seeing 19-damage crits on those with the right setup), but the damage is just high enough to combo Colonel Rangers with a grenade to wipe pods of weaker enemies (instead of doing the same thing with a second heavy weapon), insta-kill a medium-weak enemy (Sectoids, weaker ADVENT), or to finish off a larger enemy after it takes 1-2 shots. It's also balanced out by the fact that they're tricky to train up to Colonel without them dying, since they don't get their survival tool for a while.
Basically I balanced them to match sniper/pistoleers for cleaning up crowds of weak enemies and dealing very high single-target damage, with a tad more strength because they're inherently much riskier to use. The chain-killing is really good if the damage holds out, but I've nearly lost one Colonel doing that already when they got stuck in the middle of an open space after their damage fell off too much.
