I hate this rule. Logical, but bloody annoying.
My Lord has the MoT and I wanted my terminator chosen to have the MoCU but NO, I'm not allowed. I had to waste 45 extra pts to give them the MoT too.
Anyways, I was thinking... could I give the Lord the MoT and the Chosen the MoCU and just let the Lord walk around with them? That way he's not joining the unit, but still has the same effect right?
