They are good for absolutely nothing at the moment. INNO announced months ago that they intend bringing in some sort of defence capability to GBG. Whether it will be along the same lines as it is in GE, or something else, no one knows. Also know one knows when this will happen, or if in fact it ever will happen. But regardless of that they are giving us these blue defense boosts with little green flags that we can keep in out inventory and admire. You will find once you have been in the game longer that this sort of thing is not all that unusual, and just something else to be ignored.
