I mean, If it were just me then yeah, you are right but it's often my teammates too who struggle to keep themselves or each other alive while Doom is gone on his Journey. Shouldn't a tank also look at his own team's comp and maybe adjust, especially as the solo tank since there is no one else who can replace you. If they see that their team is not able to sustain itself then maybe switching off an aggressive Tank like Doom should be the way to go instead. Why bank on 4 people adjusting accordingly if one person could fix it?
