I will confess, the reason the battlefields are the "give and take" narrow types is so that I can monitor it easier and summon back those who exploit out of the walls. Though yesterday's field was definitely not my best... I overslept and was pressed for time, and I made it a bit narrow
While Tatooine is gonna be a hard planet, most all of the future battles are going to take place near bodies of water to help deal with the fire issues.
