Boss fights rewards

[Morndawn]

I like the new Jupiter boss fight, so I regret that without grind there I will not do it again after I will get all the drop. The only chance is Sortie. 

So I was thinking: the only reason players do some mission over and over is if there is non forced best drop of some wanted resources, or best xps, if they can choose which one they will do based on the best secondary drop they want. But all of it is now behind dark sector ordinary levels. So would it be good if boss fights would have some reusable good drop? I think it used to be 100% chance of rare resource of that certain planet, but after Ropalolyst dies players are instantly transported, so quite often I didn't get all the drop on the platform. But could they all drop something else reusable too?
