Recently started a PBEM, and am using the Imperator options for the first time. I am playing Pompey in the civil war. Directly at start the Caesarian troops lay siege to Marseile. The surrouding regions are pro Caesar - reason for me to send out the Punishers. Just 1 in 5 fired, but it is free, and I get 1 NM and 25 D each time it happens... and those regions aren't going to love me anyway.
Only thing that is a bit odd, is that I am under siege in the town, and I still can send out those Punishers to the 5 adjacent provinces each turn..... So I propose to add a condition to this option, that the troops that are needed in the region (or the adjacent region), for this option to be valid, may not be under siege.
