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.
if it makes you that angry that the party can surive without you then start doing your homework then start learning the encounters an memorizing them.
or how about instead you just ask the development team directly to give your job an auto raise ability so that if you do make a mistake or lapse in judgement you can recover an try again is that so hard to do is it really?
the tank is the fail safe and the literal shield of the party its their literal job to carry if the group looses its healer stop being bitter for your lack of judgement or ability. learn to be humble an apologize for your errors an thank the actual tank for not making the entire team suffer starting over from the beginning of the whole fight. if the group unanimously decided to restart then thats fine but if they say its fine to let the tank carry leave it be an move on with the rest of your day this isn't a pissing contest you want that then go play PvP then you can be as useful and contribute to your hearts content an no one belittle you or think less of you for dying as thats just how it is with PvP "kill or be killed"
