@Skenderaxe I can see where you're coming from with the invisibility being too strong; I was hoping that the invisibility could be a single use characteristic for new fences but considering how much damage fences do now, they would need to lower damage 12 instead of 15; or they would need to make the nodes more noticeable (like give it a shining static effect).
Out of all the things I suggested, I personally like number 2 because we won't need to get out of cover to attach nodes.
