I don't consider inspirations to be anything but what they are: a temporary measure. What IO grants mez protection? Can't think of one. Plenty of mez resistance but that means fark all. CJ for Immob, ok. Acro for KB and 2 pts for Hold, sure. Where's the Stun and Sleep protection? And RoP is also a temporary measure only up 1/3 of the time.
Hasten still isn't inherent. Never will be.
I am against power creep. The tank buffs are a prime example of power creep that did introduce problems with AT balance. But I'm also for QoL changes that make sense. What I don't get is the, in my mind, completely unreasonable stance that squishies shouldn't get mez protection at all when 4 pts will only be enough to shrug off a single hold. Hell, even Def - FF - Dispersion Bubble gives 8.65 pts to Hold, Stun and Immob. The other defenders can't even access 4 pts from a pool?
If anything, it would be a QoL change that does nothing to end game AT balance. On top of that, it would soak up another power pool slot reducing the number of other pools they can access. And those in the future asking to make it inherent can go eat rocks.
