Dropped inputs are still happening often in content with a lot of monsters on screen.

Instant skills, movement skills, skills being held down, etc. will frequently drop inputs and do nothing when pressed. This is most obvious with breach + delirium but will also happen during other high monster count content like legions + breach. It can often take several presses to get a leap slam or frostblink to occur and I've even witnessed vaal molten shell not activating on press or regular molten shell which I hold down while in hectic content. Network and game performance are stable when these incidents occur and there are no delay spikes on the F1 meter. FPS is usually at 60 frames if not 70+ when this occurs ping is consistently at 60 almost all of the time. Frame delay is always at 13ms.
