i got some
on valhalla, forge a reciever node on top of one of the buildings, then put a sniper up there, on the pit, there is a really high up window, i'll try and get crabroast to explain it, you can put a few random teleporters around on construct, put one on a bit that sticks out, but its not that good, its hard to shoot at you but you can't really shoot them at all, its more of a safe place, but you can get shot at, also on construct, forge a banshee, and fly towards one of the thngs on the side, do a spin trick and you can go in, if you do it right you can stand there, but mostly you'll probably fall to your death whilst laying on a ledge, on last resort you can forge a giant crate with a hole in it so that the hole is going vertically, put a closed giant crate on top and a 2 way node inside, then you can refresh and escape...
that's all i can remember off the top of my head, i'll try to find more...
not exactly that but like without forging ust finding hiding spots
