expedition is becoming kinda pointless

ok it can be good money and tujen is always good to me, but the other half of the mechanic (rog/gwen) feels kinda pointless now , rog's role feels kinda pointless due to the tree, and gwen is even worse since i feel like the gold gamba is the same thing but without having to farm her artifacts , do you think they will get buffed or will they just get changed eventually?
