Inspired by an idea from a new formation suggested in a different thread, how about this new rule
Seeds of Confusion - Maelstrom Missions only
At the end of each enemy players turn roll a D6, this numbered objective switches with another randomly determined. So, on the roll of a 2, move marker 2 to (rolls D6 and gets a 4) marker 4 spot and vice-versa.
The fluff behind this is throw the enemy off, scupper their tactics, send them in the wrong direction etc. But on our turns we know where we are headed
I think this would be great fun
