Yeh, this is a common theme for how things are I think. It's like the long range shotty cannon build. Maybe a bit OP. But ultimately, is it better than the Exe when the Exe can have 10 shots without ever reloading (2x on dom with stowed)?
Just checked the recoil on the tormentor and it is sort of static when spamming the trigger. It pulls up on the first shot but stops at a terminal height above centre. So I am not certain it's "cumulative".
This is an image (using ADS, spamming, at the same range as the picture is taken):

Cumulative should look like a line going up. You can see in the image there are only 2 contact points (top dot is multiple hits in sequence).
I think I just naturally adjust once in my head without thinking. I tend to use WASD to aim as well as mouse, if that makes sense. It'd be interesting to see how much better stability makes it though, just firing full auto at a wall. If it's much closer to the first hit, I'd say it's worth it, definitely.
