So the mass shader deletion is welcome, but there is still an underlying flaw in that you will still be constantly rewarded with the same garbage shaders you never want and they will still take up an inventory slot until you keep dismantling. That is basically a band aid.. my shader space is 47/50 with 10 shaders in the vault.
I think a better long term solution would be having the ability to blacklist/ban certain shaders from being given to us in the future. No one wants Atlantis Wash or Blue Geometry.. but we will constantly get them.. resulting in us still deleting them over and over for eternity. Having an option on each shader that would let us block it would be very welcome..
