Me I am abbandoning Metal, most of my stuff now is 3D printed. One of the great things about 3D printing, vital to folk like me is generally it bounces and remains untouched. Drop metal and you have had it BIG TIME damaged paint and broken appart metal.
The other great advance to a Dropper/Loser like me is the new Twist lock Turrets on AOTRS Shipoyards stuff (I cajoled him to make this change) now I drop less turrets, its not that they break but you can lose them or tread on them when you drop them.
My buildings are card, again drop proof as well as taking up no space. None is a cure but all help to mitigate the effects of dropping.
