The good news is if the Hach lead them to a Equestrian world they wouldn't be effected by there ability to track warp jumps. The Equestrians enter another dimension for interstellar FTL, which is also magic based. Also on that note most nations have fleets numbers in the millions, but I don't think you should or otherwise you have a lot of really hard to destroy ships that would outmatch the power of the Dracs.
