Hey there RealDude,
I apologise for the late reply. I just got notified about your response about 10 minutes ago per email.
I recorded a video that includes footage of both the shooting range and open world; you will be able to see that the Mantis weapon talent only applies while performing a headshot when the decoy cooldown is already in progress. When you perform a headshot while the decoy skill is still active, upon running out the decoy receives a normal cooldown and the buff disappears, which is not intended according to the talent description.
Here is the video:
If you have any further questions or need more footage, feel free to ask.
Thank you,
Rakmarok
Also, something else I discovered; when you equip an apparel loadout you automatically retrieve the items of the same loadout slot from your stash.
Here's the video, pay attention to my inventory capacity and what loadouts I stored in the stash:
As you can see, the items from the corresponding loadout slot get added to my inventory automatically upon pressing X to wear an apparel loadout. My "Field Medic" apparel loadout is on the same slot as my "Fire Support Medic" Loadout, causing it to automatically get transferred from my stash to my inventory upon equipping the outfit.
