Maybe
this video explains what I'm trying to say better. I am not talking about 1 shot mechanics in Savage/Ultimate. The healer cannot do much in those situations. I'm talking about deaths that can be recoverable and wipes that can be avoided.
If you have a bad healer (which I did have twice in the past). Most of our wipes were due to the healer making wrong decisions and not healing properly. That was the time when I realized that healers actually have a responsibility that many tend to not see.
Maybe most people assume that this is common knowledge and that all healers should be capable of doing this. From personal experience, this is not as common as people think.
I've had my fair share of
run to the wall wips because we couldn't recover from something that was recoverable.
You can blame the players that made the mistake in the first place, but mistakes can happen even after clearing content/while farming. At that point, you're at the mercy of your healers. If they can pull it off, good. You may be able to secure the run. If they can't, you'll only go as far as your healers allow you.
