You know you can ultimately fix this issue by positioning yourself around the mob, where your backside it twoards the RNG (Not neccessairly between the mob and the RNG for Conal AoE Issues).

Rng pulls hate, mob moves, says you cannot see target, WS does'nt go off, no TP lost, have a cookie.

I would not want to change the current system away from this, because it works on the mobs too making kiting situations safer and more viable.
