I would love to see some of the damage from artillery and airstrikes go through buildings, even if the environment isn't destructible like battlefield and such, I think it would help gameplay a lot if the damage from these incredibly powerful attacks wasn't negated by standing inside a flimsy grocery store. Similar to Insurgency Sandstorm the damage taken could be reduced significant by going low to the floor and moving away from doors and windows. Have kind of an AOE to the damage that would go through ceilings that way air striking a building isn't a complete waste if the enemy is indoors.
