Cells boost lights and bypass need for TH and/or procs for the most part (other than white for KIs, which is easily done during campaigns.)
Displacers neuter the mobs and make every fight other than Provenance ones {Easy Prey}, plus they now stack to 99.
Prep work = profit. Just like most of this game, and any other RPG.
Increased drop rates would be nice, mainly to allow for soloer's to get their own reforge mats, but I honestly don't think we can expect any sort of genuine adjustments to VW.. And honestly, the amount of content that the vast majority of 119relic would be useful for as more than a macro piece is pitifully small and out of date to begin with, so you should be looking at them as only macro pieces to begin with. Even Escha-Zi'tah T1 armor sets tend to have better stats for general use than reforges.
