I like the style of the maps, and I think you're doing this and it's just because of the first mission you're revealing most things, but specific details should be left out so that we may find them out, maybe during mission or sometime of mini-op to gather info on our next objective. 

Sizes are mostly whatever to me, as I believe they'll probably vary from mission to mission yes?

As for situational assets vs isometric views I such, if you have the time I think it'd be cool if they varied.

And while we're on the topic, will there be a chance for missions where we run solo or break into smaller groups?
