Recently, we added Cone of Fire adjustments based on your character's movement state. We did this because, put simply, guns were performing far too accurately when running and jumping. Philosophically, our belief has always been that aiming down sight should be the most accurate method of aiming; this change made sure that's the case.
However, it was also possible to aim down sight while jumping, which also allowed for tremendous accuracy in a way that didn't make sense. This update addresses that issue by preventing ADS while jumping or falling. This has also allowed us to ease up on some previous combat restrictions around movement and it will now be possible to shoot and ADS directly from sprint. You'll no longer have to wait for your character to slow down and suffer a delay when trying to shoot.
