Just out of interest, which rules are you using to play the games and at what level (i.e. section/squad, or platoon+)?
As I play my 15mm games in either a 60cm x 60cm or 90cm x 90cm playing area, I tend to ignore ranges as they will cover the playing area regardless.
I personally go with the ‘more scenery/terrain’ option, but I have considered using a grid map with ‘blips’ on them and placing figures on the playing area only when my blips and the enemy blips enter the same square on the map.
This allows for deployment and movement without the long range weapons to dominate.
