Shaco Boxes Stacking

After messing around a bit trying to figure out what direction boxes would bounce in I noticed if you were to have enough in the area boxes would eventually stack up on one another. After about 5 boxes in a line I was able to recreate the stackable boxes consistently however for best results use it near a wall as the boxes have less possible options to bounce to. Stacking boxes in this manner is very pointless as one would have to babysit the area and ensure nothing would interrupt the previously placed boxes aswell as the needing of high CDR + AP.
