Personally, I don't mind large forests, in just cases that's what a lot of battlegrounds will end up being. Maybe with one if two differences, or a slightly more descriptive telling if it. A large forest, a empty field, volcanic plains, so on.and so forth. I DO get what you're saying though, but I would limit it to essentially copies of each other. 

cool. I'll see if [@Heyseuss] can sticky it for us. As well as this thread.
