I main support (mostly) and it comes with a feeling of helplessness in RQ.
In RQ all it takes is your team getting a scaredy cat tank/bad tank or DPS who don’t know how to aim ((rarely landing kills) or a new support player who unintentionally throws. There’s so many things which can go south in RQ and it only need ONE of those to occur for your team to get a hard L.
In open queue, I can change my role to try help address the obvious issue out. In RQ you’re mostly locked into a outcome.
