In general I would like to have better planning tools, e.g. a LOS-tool that doesn't require me to first put a unit at a certain spot an then issue a target order. I'd like to see what the LOS is from *any* spot on the map, in order to better plan my advances.
Likewise, it's sometimes hard to predict what route my troops will take when given a move order (e.g. where ist the closest man-sized hole in that bocage?).
Again, this would greatly help new players. Maybe not totally realistic, but it's just frustrating to have to reload because that ridge I movoed to didn't end up offering the field of view I had expected...
