Unless that's from some big spike damage (T6 swarm, T8 lasers), you're reactively healing. If the tank took that much damage, the fairy will be throwing an Embrace at the tank as well for 700-800 recovery. Then there's only 1200-1300 recovery remaining, perfect for one Cure 1. A crit would mean overheal for you or the fairy, which is equally useless. Even more overhealing (and mp/gcd waste) if the scholar throws in an adloquium or physick as well.
In a real situation the tank is usually taking constant damage and heals have to keep them high enough not to die. The damage the tank takes varies greatly depending on boss crits etc. There is no way to predict every hit the tank is going to take and cast a perfect combination of heals for them. There's also no way to predict the exact combination of heals the other healer will use. That's why it makes no sense to say "in this situation you'll need to cast 2 non-crit cure 2s, then 1 cure 1 and then 1 cure 2 again". It's also not "late healing" or "reactive healing" to choose to not heal tank to full right after every single auto-attack hit they take. What I aim to do is keep tank in comfortable HP range with cure 1s and regen (and stoneskin before ravensbeaks, for example) for as long as I can, then using cure 2 if they get dangerously low. It's effective MP use and crit does help with it.

What I agree on is that crit is not something a WHM can rely on in the sense that you shouldn't count on a heal critting or otherwise the tank will drop dead. However, crit is far from useless and getting those crits makes it possible to go on for longer with cure 1s and regens instead of having to use more MP consuming heals. Piety has its merits, but as long as you're within comfortable MP range to get through a fight, the rest of it doesn't really add anything to your power. I don't find spellspeed to be useful for my healing style. So DET > CRIT > PIE > SS it is for me.
