On the topic of possible changes, they have apparently said multiple times that all armies going forward will be forced into what is available in their boxes, like they did with Stormfiends so Arko's will go to having only one of each weapon if they do the same, my belief is that they will change the unit drastically in some way to compensate or the book as a whole.

Sadly I can't change the list, but I would agree those changes would be great!
Yep I do get a second artefact but its a variable campaign artefact the TO generates at the start of the games.
The Gunhaulers are my one acquiescence to the "objective" style play, giving me mobility to cap/contest or pressure objectives, not to mention a descent cannon shooting round can do some real damage.

Thanks alot for your reply precisely the type of thing I was thinking of, I'm not so familiar with FEC, I've been reading the book but its hard to mentally grasp something until it actually happens.
