I ask myself that same question, and why is Modus Veritas a proc, SE already nerfed it to hell so it never lands, procing with that is rarer then getting the drop you actually want off the NM!
I stopped trying to use RDM in VW for enfeebling procs because one day a taru COR/RDM landed para after 30+ tries by me using para 1&2 in enfeebling gear with magic acc gear using drinks... and he did it on his 1st cast... VW makes no sense to me.
