A couple things.

Paladins are worthless without Draigo, and must be taken in a unit of 5 so you get psycannons. Otherwise, just take 5 Terminators (or 10 Terminators if you have the points to jump up from 5 Paladins). Either way, you must, must have Draigo with them, to get Gate of Infinity and to tank str 8 ap 2 shooting.

Dreadknights should always have the personal teleporter. It's singlehandedly the best thing about them. Add a psycannon for anti tank, and a force weapon. As second gun is nice, but optional.

Grand Masters are a lot of points in a low model count army. I've found it better to skimp on HQs to get more points for more bodies. Take a cheap librarian and be done with it. Use those points to get Draigo or upgrade the Dreadknights.

Unfortunately, GKs are very monobuild. Practically every list is a librarian, draigo, 10-15 terminators, and as many dreadknights as the detachment allows. Maybe some allies.
