During regular stamper phase. We have noticed that we could stand in on the strips in between the belts.
If the part on your right for example gets a stamper on it. You can stand on the left side of the strip without being hit. Try it out on LFR to see if you understand what I mean since I find it pretty hard to explain without having pictures etc ready.
But those strips you can use to stand on if you just move to the sides of it. If you got any questions just inbox me and I'll see if i can show you in game through a stream or something
