Crazy idea, but maybe someone who wields The Coordinate to its fullest power can not just control dumb-dumbs but they can actually Titan Shifters.

Rod Reiss mentions that the holder of the coordinate at full power possessed a sort of god invincibility and so far we haven't been told exactly what that means. The curse could mean that the titan shifters from the homeland aren't free because they live in fear of being dominated every time they turn into a titan.

But, pretty much, at this point, we can only speculate, we are very far from the whole picture.
