A while back there was a bug that allowed a hijacked enemy to trade weapons with a player which allowed the player to do 3x damage with the AI’s weapon. Obviously this needed to be patched and rightly was but the unintended effect of this is now when Jack hijacks an enemy he does not get any damage bonus like he used to.
So if you take over a enemy now compared to before this bug was patched your damage is next to nothing. And the only real use of hijack now is to combine it with the skill card that kills the enemy after the hijack ends, Also this makes the new skill card that jack gets to deal bleeding damage with hijacked enemies pointless, as well as the previous one that extends hijack time with kills.
Solution: Simply allow hijacked enemies to maintain their damage buffs without making them able to transfer the weapon to a team mate.
As jack is right now hijack is pointless to use for offensive means and its only good for killing one enemy by hijacking and canceling the ability.
Of course this is my opinion but I feel this should be addressed to make jack more viable on higher difficulties rather than being stuck to being a smelter and healer.
