What I have noticed is that the specialization called salvation for revenant , the outgoing ally healing increase to be exact , it does not seem to actualy be working or scaleing at all with the tablets healing. I know for a fact because I have done test with teamates in actualy matches and useing the fire to hurt them in the mist. Also I have noticed that sometimes the tablet will become invisible or even just not follow but letting me use the commands and still working, though since I cant see it I cant use it properly
