Stun "Immunity" Evasion Mastery Question/Suggestion

Hey guys, I'm wondering about the evasion mastery: "Cannot be Stunned if you haven't been Hit Recently".

Correct me if I am wrong, but in my understanding an evasion character will get hit by spells all the time (spell suppression will take care of that), thus rendering this mastery significantly worse because it will be disabled constantly and by a type of damage that can't even stun right?

So my suggestion would be changing the mastery to something like: "Cannot be Stunned if you haven't been Hit by Attacks Recently".

Would this make the mastery broken and I am not seeing it?
Does this change make sense?
Is there nothing in PoE that exclusively refers to "Hit by Attacks"?

The current one is crap for the exact reason you've mentioned.

If however they change it to what you suggest it becomes stun immunity on boss content for 1 mastery point which is extremely good.

I don't know what the answer is, I actually would have preferred a generic chance to avoid stuns because you can add/build around that to some degree.
