Ok just throwing it out there but staggering is literally the reason for about 50% of your games being lost.
I cannot describe how irritating it is to have your team just constantly stagger and not disengage from a fight and Overwatch need to highlight how much of a problem it is.
When you stagger you are literally making the game incredibly difficult and wasting time. I have seen all these tips flying up on my screen when I die about how to use an ability or to watch out when playing into a particular character.
WHERE IS THE YOU HAVE DIED FIRST IN EVERY TEAM FIGHT tip?
Seriously, just reporting for gameplay sabotage every single time I see someone just go off on their own, die and then repeat it till we lose the match. Overwatch needs to do more to highlight how bad it is, why not to do it and how it should be reportable.
