Vect Wasps are not gaining the skills they have gained from their update a long while ago, when turned to mercenaries. I'll assume Golden Beetles also don't get Rail Shot. I'll edit this post otherwise.

Mercenary mobs do not get skills they are normally supposed to obtain past a certain level. I've asked about this before and it seems entirely intentional.

Ah, I see. It opened the doubt mostly due to how the new implemented mobs (Ooze Bois 'n Snekeaters) come with their full kits.

I'll leave it as unsolved for the time being, perhaps for the latter to be called unintentional or not too.

Yeah a lot of new mobs have been getting their full kit at level 1 instead of progressively getting more of their kit as they get stronger.
