You just have to look at the team comps in QP, especially 6v6 I find, to know if you’re probably going to have leavers.
- pharmercy : guaranteed at least 2 leavers from the other team
- sombra : guaranteed at least 1 leaver, usually more, unless sombra player really bad
- mauga : pretty much guaranteed leavers, although more in 5v5 than 6v6
- widow : not as often, but I do see supports leave after she dings them once to many times, especially if spawn camping
- mei : I’ve seen tanks leave against mei but I’m not sure if it’s just her walling them off or if it’s in combination with other anti-tank heroes like ana and then the combination is just too much. I’ve played her a bit and I’ve seen tanks leave right after dying to being walled.
- ana : personal experience as Ana is the support I play most. if the ana player just keeps sleeping and nading tanks like hog and mauga then they either switch or they leave. Most often they switch though.
- doom : supports leave
- ball : supports leave
My last game today the other team had pharmercy. One of my supports died almost immediately to pharah and left, then the other support died to her about 10s later and left before we even had a new player for the first leaver. Pharmercy is by far the worst for causing leavers (well, pharah alone I guess. Just that mercy makes her harder to kill).
I really hope they gather stats about things like this, but I very much doubt they do.
Are there others that I’ve missed?
