BST adjustment did not address the problem, Devs please read

Yes, Hoshi. The Beastmaster must be within 7 yalms of the pet or the mob in order to execute Ready moves. However, you will still randomly get 'out of range' when trying to execute pet Ready moves depending on the size of the player, the pet or the mob. Aside from it being an incredibly tight restriction, there is a random occurrence of the Ready ability not executing altogether if your pet is not visible on screen.

Right, but if you stand within 7 yalms of your pet, directly behind your pet who is directly behind the monster which is being held by a tank or a trust tank, why wouldn't that work? I understand that depending on the size of the mob you may have to be less than 7 yalms from your pet but from the posts here it sounds like bst is unable to position their monster behind the enemy and I am wondering why that is the case?
