Cast spell, get hit, miss the save, nobody has to save versus Spirit Guardians (for example, since the save is on their turn). (As but one example)

There's a good reason to optimize if you want the spell to work.
Spoiler: about a couple of egregious cases where a 60+ HP hit didn't break Conc

( Dil's "cut damage in half tattoo once per long rest" was just icing on the cake in the late game where I was able to make a save that, with the amount of damage inflicted, normally she could not have).


Plenty of folks don't try to optimize for concentration maintenance.
Right. What I'm concerned about is when people do optimize for it. In the unoptimized case, everything's fine. NBD. But the way that caster defenses and concentration optimization stacks, it's really easy to basically be immune to losing concentration on anything less than about a 30 damage hit. And most creatures scale via attacks, not raw damage per hit. Meaning that nothing but those big single-attack bruisers (who are very vulnerable to other means of not hitting) has a hope of breaking concentration.
