This gives the ants time to learn and develop techniques instead of just being nen powerhouses though. Colt is already trying to reproduce the effect on himself while Peggy is about to study Rammot. It'd make more sense for the higher-ups to figure out abilities now and have them teach it to the Royal Guards and King, instead of having the King magically being born a Nen master from the start.Originally Posted by DE
In any case, it feels better than being a "random" event. If none of the Ants had Nen so far, it doesn't seem likely that they'd just "spontaneously" get it at this point - and only the Guards/King are left to be born. Plus, we've had plenty of characterisation so far and it'd be a waste to use them as easy cannon fodder.
