There is a bug on Whiskey Foxtrot that always bugs me when I play him for a few matches.
When you sprint and stop pressing the sprint button, a character usually keeps sprinting until it reaches a full stop or uses an action.
With Whiskey Foxtrot’s need to spam the trigger, the character also keeps sprinting after firing once.
This means that after sprinting WF tries to sprint inbetween every single burst, which looks like his weapons had hiccups, resulting in a terrible rate of fire.
To prevent that you have to get to a full stop right now, which is pretty intrusive.
