It seems via logic that the third subclass for warlock will be an arc based class (duh right?). However, post is about speculating what it will be like. I imagine Lord Sidious fingetip Darkside of the Force type power! I imagine it will be the futuristic high tech version of Zeus with a super similar to novabomb but the game gets dark like a public event as you ascend to the clouds to unleash a lightning apocalypse on the unworthy pawns below. I imagine electromagnet power from an outstretched palm to raise a single opponent off the ground and either explode, crush, or throw him/her away like a ragdoll...what do you imagine?
