I understand. If that brainless one doesn't heed your calls to leave the worm alone then there is not much you can do.
We should all have a class ready to counter the worm playstyle. 2 EMPs and 2 Blackhats should do the trick. They could have also detonated an EMP on the area beneath the room he's camping and it would have destroyed his equipments. I believe it would have worked. I've been EMP'd on Hijacked and I was on the engine room and the EMP detonated on the main deck. EMPs goes though walls and floors.
