Hi,
I presume everybody agrees that a battleplan is somwhat dependend from the froces involved? However, when defending in a resolution phase I have to make battleplan decisions without any recurrence to the force composition of my stacks involved beforhand (I don't think that many players have a photographic memory ).
So imho it should be possible for the player to consult his force composition before having to decide on what battleplan to choose, in all circumstances!
