why do people that say that always have 2/3rds kills with the msmc, a 1.3ish k/d and bad w/l from dashboarding all the time.
Why are you focused on their stats? They likely play that way because they enjoy it more than using a different gun.
Also you get a crap W/L from simply quitting all the join in progress games you get thrown in to. You'll lose if you stay in the game so why not just take the loss and move on to the next game sooner?
People who actually "play for fun" generally aren't so caught up on stats that they would have any "defense" for your accusation anyway. They're "having fun" you're posting in an attempt to ridicule them. One of those seems like a massive waste of time.
