I sort of meant that Strange would be looking for a way to stop Dormammu in the future. I didn't mean that he would fight Dormammu again in DS2.

He would just be preparing for the future, but then stumble upon Nightmare enslaving Eternity. Dormammu wouldn't really have to appear at all in the movie.
