Your welcome , and good luck . We do run Mercy in our 6 stack at times since we run a PharahSoldier combo , we use her like an initiation tool with Pharah to bobble the typical Reinhardt shields , Mei , and similar off defense when we have an issue . This way our Pharah must be dealt with but our ground troops as it were are much harder to deal with due to not being fired on as much . Might help for a duo queue finding a good Pharah though . One other thing , our Mercy does some float down shots as she comes off her Pharah on enemies since her position is superior , then flies to any people who need healing . Its pretty neat to watch , but she also happens to be our best McCree and Tracer , weirdly awesome aim and reflexes .
