Simple idea: you get an Ereptor queen that has access to EVERY ant. As in even the ones currently inaccessible (Dorylus Nigricans, Platorhyreus Tarsatus) so you can play with these ants. Or, they could add designated Ereptors that each have one of these exclusive species (so one Ereptor with only workers and Platorhyreus Tarsatus, one ereptor with only Eciton Burchelli, and more for other types of ants without dedicated colonies, like the ones the Counterparts use). I’d personally like the second option more, though it is more work from the developers side, and given the game was updated TODAY, it seems unlikely to happen in a timely manner.
