You should have change it few patches ago 
Unfortunately I cant resist the feeling that you guys from Crate are starting to run in circles. Few patches ago in the name of balancing you nerfed phys and pierce to the ground and buffed cold producing most unbalanced build ever and now you are making same mistake just other way around.
But anyway Im grateful for the effort, better even that than noting, keep up good work
From start I knew that you meant 50-80%
