Shaco Box Bug

Playign as Rammus on an ARAM, I was attempting to clear out Shaco boxes for my team. the first item I bought was to enhance Rammus's natural damage, and as the boxes deal autoattack damage I believed this would help passively clear them while feared. When being fired upon by the boxes however, bramble vest was not triggered. On closer inspection, even when I walked over a box with 's W active, the boxes took no reflection damage on attack.other forms of magical damage from pets (Heimerdinger turrets, Zyra plants) incur the reflection damage back to the pet. With the largescale weakening of thornmail, this seems to overly favor Shaco in a battle against Rammus.
