You wouldn't criticize a DPS for stacking crit because "If you're relying on a single crit to make the kill, you're doing it wrong." or something along those lines. You'd say "Is that the best way to increase your DPS?"
That is the worst logic...dps crits actually do more damage. Healing for more than is needed doesn't raise your tank's HP beyond its max.

And yes you do have to keep thinking about it as if a single parry/block matters, because that's how healers learn a fight and learn what big hits to prepare for.
