There is a good chance that by the time the wing charges, there is a hole at the center (for example, from taunt killed by flanks). Thus, SW hits all the heroes that are left
Oh, I got it :) Well, that was my failure, and it is right for me to clean my mess :) All players in GD have solid teams for oneshot and it would be not fair to ask them to sacrifice their points to hit the 38 HP target ;)
