EEVEE is not just for previews

Right behind you. I use EEVEE for just about all my motion graphic work. the Real time post processing effects like AO, GI and world reflections makes iteration and refinement of my work that much easier. I dont create hyper realistic content but more or less focus on stylised content so EEVEE has just been perfect. Sometimes I even just do a viewport render with all the gizmos turned off and the result is just as good.
