How would you *fix* battle content?

i do not agree with this take its not the tank's fault that a healer may suddenly die in combat people need to stop asking to take things away from jobs i know healer mains are angry and for a good reason but they dont need to blame it on other jobs or players
and just because it might make you personally angry that you can't contribute cause you were not paying attention to the encounter or because you made an error doesnt mean everyone else needs to suffer for your mistakes.

It's not about shifting blame or really any of what you said there.
A healer absolutely knows that they died because they made a mistake.
But a tank should not be able to survive without a healer, simple. Just like a DPS can't.

There is no blaming happening, but what is annoying is that IF mistakes are done which literally are unavoidable, the tank is still there soloing stuff just cause they can EVEN when they make the same mistakes.
There are times where I would personally much rather take the penalty and leave a duty, than watch a tank play solo.

You say it isn't a pissing contest, but the literal notion that a tank does 50% of the fight while the rest of the party is dead is the literal definition of what a pissing contest is.
EDIT: Just to clarify I don't mean that people take it as a pissing contest and get angry because you can solo a boss. But that you are doing something just cause you can.
