But wait, I don't want to have my characters in a tower to unstack w/out
putting up a fight so lets do that too, and ok I can try to take control of
the tower from within, and _these_ units will fight against the other units
in the same stack, and... *blech*
Considering the problems that would go along with units in a stack attacking
one another w/out auto-unstack, better to just say you can't do it. How would
a player feel if he was told that all of his units on a ship were completely
destroyed because the stack leader changed attitudes?
For the other side of the argument: how hard would it be to implement
'stacks within a stack'? Then you could have this case easily, which could
also be applied to units inside of a tower or other construct vieing for
control. On open land it makes sense to auto-unstack units that attack other
units in the stack, in a ship/tower/whatever I'm not so sure.
