Shadow Priest AoE: Please give us back Mind Sear

The Broken Shore WQ Creepy Crawlies is a pain to do solo as a shadow priest. I miss Mind Sear because it didn't need a requirement to produce AoE damage, no shadow word: pain, just push and go. The grubs have such little HP that SW: P instantly kills them so I can't use Mind Flay to AoE them down. So I have to DoT every.... Yes I could use a tome or go back to a rest area to change one single talent but I shouldn't have to. Please give us back Mind Sear or at least have mind flay AoE on its own with less damage if SW: P is not applied. Mind you, MF doesn't AoE damage on the first tick, it would also be nice if it did.
