Ticking Sack of Terror for Ranged dsp

Mr Robot left me in weird feelings about my rotation by suggesting Ticking Sack of Terror for Demonology Warlock. Should I hit with staff in melee or it’s just a wrong tooltip on the item?

We have it flagged as melee-only in the simulation, but looks like not in the optimizer. I’ll filter that out for ranged specs in the next update.
