It happens that vortex floats enemies away from the stage (don’t interrupt the skill with an attack or cancel it early with another tap of the skill button). It becomes a problem when you have to clear a stage to procced further (example - can’t progress thought Leoric dungeon). In my opinion enemies do not count as killed - elites are still visible on the map after floating away from the stage.
