Just pick around them. Any time I see Hanzo, I play pick Zarya, also for genji as well. I also might pick Ana if I see a genji. Either way, if they can do their job, I’ll make sure to follow up.
pick chracters that can team wipe zarya rein genji pharrah the win rate is high if u get good healers but for flankers and dps ain't getting it done go zen make it easy for them when u play for assist u win that's the key
