The outcome of a save is binary, but a saving throw "ability" more than bad or good. That's just 5E's approach because it only has proficient or not proficient by default. You could easily have 3 steps, bad, moderate and strong.But that also is rare.
Grapples are inferior attacks for monsters.
Few monsters have mind blasts. It's really just a few far realm stuff.
But like I said. If you go back to Fort/Ref/Will you go back to PCs and monsters being weak in 33% or 66% of saves. And that's with like you said, people still getting murked on their good save.
And if your game had conceptual design space for monsters that serve as "bosses", maybe you can even hand out more than 1 or 2 good saves to them!
And because everyone can flunk a save, even if it's good - effects should be balanced that the effect of a single failed save isn't devestating.
A Desintegrate spell turns you to ashes, but does it have to be on turn 1, for example?
Does Stun really negate all your actions, or maybe just lower your action options?
Does Dominate really mean you only do exactly what the enemy caster says for a minute ,or can you do something else?
Can a Fear spell effect you more than once per minute?
