Registered Damage Lag

[KesslerCOIL]

I've played Warframe for a few years now and the way ping has affected players has always been in favor of the player, allowing all damage to pop out immediately without delay.  
However, this patch I've noticed when playing on high ping that there is a delay between my shots hitting a target and the damage actually registering. This has gotten me killed several times now due to enemies taking longer to die and needing to chew through more ammo because I dont know when it's dead until ~0.2sec after my shot has hit them.  
  
Were there any networking or input changes made this patch?
