As I demonstrated before, playing BK at the levels you can recruit the new units the xp gain and loot will be comparable to playing only the Lost Skull at level 50, thus being mostly a waste of time despite of its low losses and difficulty. If you fear people hoarding millions of granite, just remove BK from the store. Then the fact that you can have only 21 scouts will limit your BK'ing a lot.
However, of all the possible issues the worst is to have a third separate army and the fact that those units cannot be mixed. I wonder where Ubi/BB hire their game designers. There are dozens of solutions to fix all these "balance" and inconvenience problems, but somehow BB is unable to find them.
