Im not sure if it was patch 4.6 itself or one of the hotfixes patches that released later but now i constantly multiple times per game get enemies that spawn around me so close to me that they have already played their animation to hit me or they actually spawn inside me and do the same thing, always with no sound. I have also seen the same thing happen with specials but very rarely.
I will give 2 examples because i dont want to be typing for hours. I had a chaos warrior spawn partly inside my body and instantly hit me with no sound as i was move teching with my weapons and on another map i had 2 SV, 4 trash enemies and 1 mauler spawn right behind me with no sound and instantly down and kill me when nothing was in the area.
Almost 5 years and the game is still in a beta state as far as im concerned. Im genuinely angry about how much this bug has been messing up the games im in.
