So, no Dormammu means no Kaecilius as a Mindless One then.

Also, I think only Thanos with the Infinity Gauntlet can kill Dormammu. If he does return, either Strange will do the time loop trick again, or else he'll be unstoppable. And if anyone's gonna kill Thanos - which they won't, if Kaecilius is still alive it means Marvel is consciously not killing Phase 3 villains and Thanos is a recurring main villain who always survive - it'll be Dormammu, but someone else would have to call him to Earth first since the portal closed after he absorbed Kaecilius
