I have recorded three matches. Last night. Double Agent. In Shock. In Shock. That sort of bad luck is astronomically unlikely. I don't think the problem is likely to be the gun. It is more likely interactions breaking the code.
I would be on board with the bad luck idea if it eventually ended. It hasn't. I've literally critter in one match playing with different cards.
I'm just saying with a full clip I should crit 98% of the time once. I shot something like 1500 bullets yesterday without crit. I should have critted 250 times. I've crit 0. And the above example is just about YESTERDAY, not the days prior. Six shots per clip, 20% chance to crit per bullet. One should crit. I'd be satisfied if I crit every now and then just 1 per match sometimes, but it is nothing. The thing is broken somehow MORE THAN LIKELY. There IS a slight possibility it is just bad rolls over and over, sure. But take a d6 (which has 1/6th chance or 16% (less than my vortex crit chance) and try to roll it 4000 times without a 6.
Or...Buy me a lottery ticket? HAH.
I'm just saying the likelyhood of it just being bad luck is approaching 0. Every shot I take and don't crit that idea has less value. So, maybe check its interaction with the cards I use which is Harmony and Stoicism. If that's not it, see if anything about locked cards pre-patch could mess with new code. A friend has reported no crits on Warm with Hans while using a prepatch card, as well.
Or, if you really wanna go nuts, just replace the Stoicism I have with a brand new one...no functional change, but rolled since patch, and I'll play test it later. Hah. Because I've critted using different cards once. In one match out of all the ones I've played with Vortex and Iune. , I've used different cards 1 time with Vortex. And I got to crit that time. Heh.
