because I throw my Q and E to start the fight, and when I start a fight I always have a full magazine (I constantly reload). Putting on the W allows me to refresh my ammo mid fight and prevents those scenarios where I don't kill someone and stand around reloading for 4 seconds as they fortnite dance on me.
