Would you like an in-game parser?

I usually throw asylum and medica2. So if it happens I use instant aoe heal.

I usually save asylum for the ukehi after it, since it hits multiple times. More often I just have to swift or precast medica or even c3 to get people up after a flubbed bolt, and then a fast cure to the next marked target. But either way you need to react pretty fast to read that the person doesn't see he has the marker, and then act correctly in a matter of seconds. It's not really easy to do this, especially after the sixth run.

If these huge mistakes (including a mostly dead group) can be overcome by self-proclaimed casual healers I don't think the argument can be reasonably made that the 4.0 ex primals are not faceroll.

..if you are farming ex primals when they are relevant, to the point where you feel ok solo healing them, you aren't a casual healer, good lord.
