OK WHEN IS IT NOT MY FAULT? (when I play as a DPS)

For reference, I am a flex player so I play dps half or less of the time, I main psylocke for dps. I am first to get blamed whenever the team performs poorly and then they start requesting things like "focus the tank", "pick the healers", "healers are getting dove fight that". Now obviously there are times when it is the dps fault but also I cannot do everything you are asking of me, I cannot protect our healers and get picks on the other healers at the same time. Idk sometimes the team is just not coordinated or is just worse at the game but I am the only one to blame (only when I play dps). When I play with a coordinated team I always end up with the most kills on my team and compared to the opposing dps.

The finals straw to making this post was my last ranked game (in photo) where I was fighting the other teams hulk and spider man, and the team was wondering why i could not kill the iron man and why I am shooting tanks. I shoot tanks to reset my cooldowns (psylocke) and I am protecting healers from hulk and having to 1v1 spiderman. For some reason not even the other dps gets any blamed and its just me because scarlett witch "is not a dps main".

I just want to know if I am coping or I am somewhat justified in the point I am trying to make.
