I think as it is, it's alright, though I prefer how Solasta did it - feels a bit more impactful, and easier to understand what you get, and how each class differs.
I just think 2 is not enough and doesn't encourage short resting enough.
With story content being tied to long rests, I don't think you want to discourage long resting any more - at least I don't want to discourage myself from long resting.
