I think fixing them to not screw with spinebreak as most allied mobs are smart enough to not screw with normal knockouts is pretty reasonable and not that hard to do.

I think swimming hordelings or auto-giving them boats would be a step in the right direction, too. It doesn't seem reasonable to have to grab fifteen boats for your horde to me -- it's just too much a pain in the ass.

Horde having the chief's PK is probably a good idea, too.

I can't remember that much about the mechanics of Rally at the moment so I'll skip commenting on that for now.
