Questions about Fire Godlike passive Battle-Forged

[Nanomachin]

I'm a bit confused as to the effects of this passive, and I don't know if the current behavior is the result of one of the game's bugs or if it's really what this passive is supposed to do.

 

Currently, at PL 9, the result are as follows : it still only gives 1 point of armor rating, and the counter damage it produces is increase in accuracy by +18, has +2.3 penetration, and no bonus damage.

 

I can understand why the armor rating would not increase with powerlevel, that would probably be a bit too good. I do not understand however why the damage portion of the retaliation ability recieves absolutely no bonus damage to help it scale in the lategame.

 

Would anybody know for sure how that passive is supposed to work and if that's the intended behavior ?
