As a very green newbie to the game, I was wondering if spreading your units out across a map zone, just so you can visually see all the army, corps, divisions, brigades etc as individual counters has any effect on their performance in battle? Or whether they act as the single stack that the game defaults them to.
At the moment, I'm learning big time, and I prefer to visually see what I have, rather than have to investigate a stack of units to find whats there.. so I spread them out manually (I have no idea if there is a way to automatically keep units apart visually - but the game seems to autocluster them into stacks).
