Storage skill

I'm not quite sure if this is a bug or if it's intended, but I have felt that since last update, the effect of a high Storage rank on equipment durability loss has reduced greatly. Even a very high storage rank, my equipment is losing one point of durability nearly every month. The worst is for equipment which can't be repaired using MTTs or MSTs and is hard to obtain. Now it breaks down much faster, I have seen. I want to know if this is part of the update or a bug, and if it's going to be changed
