Someone on another forum pointed that skill cooldown gear failed to work for him, so I went and tested it. (He is on Xbox1 and i’m on ps4)
The original post was : Basically I don’t think any cooldown reduction ITEMS work. Like at all. I tried it with Montana and my findings were this.
"The original cooldown for his frost mini gun is 16 seconds, that’s like as soon as you start a match now I had 2 items that gave me : 4.20 and 4.80 cooldown reduction for a total of 9‰. However after buying the 2 items my cooldown was still 16 seconds. At 9‰ it’s should be about 1 second off or 15 seconds. However if you choose a mutation that says 15% it usually drops it a good 4-6 seconds. "
I just tested it with Oscar Mike and confirmed that the skill cooldown item doesn’t change anything. On both skills. I also timed in case the countdown itself was accelerated, no changes. Anyone can confirm that? (I’ll upload a video a bit later)
