Not a problem my friend. The arena needs more than one terrain & there's not a lot required for a functioning WW1 terrain. I plan on doing 3-4 in the next couple months just so the arena can get some kind of rotation going.
I know you have incorporated low and heavy cloud into some of your offline missions is it possible for the online arena,the four seasons would be good for the 3-4 terrains you mention a snow covered winter terrain would be awesome.
Thanks Ranger your for your skill and time.
