A couple of ideas and no more. Its noticeable that building proper fortifications in this game is quite difficult in my opinion, you rarely have time to put anything up before your getting shot at or blown up. Maybe when playing checkpoint and capture the flag games you could put a minute or two where attackers cant advance and for the defenders to build something more advanced than a small wall of sandbags.
I thought it might be a good idea to increase the range of fortifications that engineers can build as well. So build a high wall of reinforced sandbags or
stronger structures that has peepholes for shooting with snipers and Maybe something like a platform for shooting personal mg’s more accurately. Something that strategically placed can be a real problem. Like reinforced sandbags that take more resources to build but will last much longer and is more practical. Engineers can in real life build more than a small wall of sandbags. maybe be able to put camo on them as well. The current sandbags i can see only very limited use for.
I thought it m8ght be a good idea to have semi large structures that can be altered in size before actually building as well so it fits in the space your building in.
What do you think?
