I really hope they make non-playable ants playable in Freeplay someday. That'd make the troop choices a bit more interesting, leading to better replay-ability.
They could add the freeplay into some “rogue like” this isn't needed but if so. People get jelly from resources, killing stuff etc; to get species like Army Ants. Of course, this is clearly isn't needed. (Or we can choose our species gene thief but what ants.) Whatever the case, yet again. This is NOT needed and the developers should now really be focusing on what's planned and wait for the finished product.
