When the defense pass hit us last year the armor you wore actually mattered. Heavier armor meant more PRR and served a purpose.
Now? Between planar focus, blue augments, and soon-to-be every kensai having Earth-stance 4 and 50 PRR from low-hanging Shintao fruit the type of armor you wear is pretty irrelevant.
Isn't this what was complained about by the devs regarding the old AC system? That your armor didn't actually matter and it was all the stacking non-armor bonuses that broke the system?
We're now at that state in the game with PRR. Congrats devs you just broke your own system by having history repeat itself!
You're armor should matter more than it does. Make it so.
