Oooh. That’s reminded me of an old idea of mine.

The whole “bribing” Melk thing doesn’t seem to fit the whole bounty hunter theme, at least for me. He has a range of jobs that need doing, we should be able to pick which ones we want to do.
The only reason money comes about - seemingly - is because this is yet another cash (aka) time sink mechanic linked to rng.
Mini Rant now… 
TBH When I think what they could do with Melk - e.g. objectives a bit like mini-penances - I think his contract part of the game is poor. Where’s the kill demonhosts specifically? Or kill specials. e.g. What’s that? We’ve a set of active map conditions with snipers/low viz in the maps? Ok → let’s have some quick sniper contracts for a few hours.
It’s just not joined up in to a cohesive world imo. We have the game which is ace (10/10): then we have these things around the side that are supposed to incentivize the game but do the opposite (3/10).
