After viewing that it gave me two ideas maybe I will try and formulate for wishlist later.
First, in WWI arena instead of showing map of enemy bases (similar to the way task groups are not visible to enemy), experiment with reconnaissance aspect of WWI. Some great terrain makers around, so make the terrain be the guide to target instead of the clipboard map that we are so comfortable with. No ground vehicle base capture component so forests could actually be solid graphic objects (more like elevations) along roadsides, rivers, mountains, other visual clues, etc.
Second, give the WWI dweeb something to do in an almost empty arena. Give him the (yes, you guessed correctly) Zeppelin! Since there are no real strategic targets to hit, give them one that is just plain fun to watch go down in a blaze.
