60 Ore for winning five games as Monsters is rubbish, though. I always swap it out; how can I win as a different deck, when it's so difficult to build a competitive deck with that faction? It's too late now, but winning as a faction should have represented in the Reward Book, i.e. you would have to win as Gernichora to progress in the Gernichora tree, with the ultimate goal then being a truckload of scraps and the new leader skin. All leaders should be available as standard, and they shouldn't be mill-able.
As it stands, I can create the NG hyperthin, win feathers, unlock whatever I want. It doesn't make a lot of sense. A new player should be able to win a few matches and build a better deck. Every keg should have a purple or gold in it - it's ridiculous to churn through a dozen kegs and just get duplicate bronzes.
The latter point I agree with, here's my own recent example - played a game with ST/Eithne deck I built, nothing special, but fairly enjoyable due to thinning (when you get a good deal!) as I prefer to reduce RNG. Was matched up against ST/Eithne. I got absolute slammed at some point by Schirru; had about 30 points wiped out in a single turn. So I thought "man, I really should have Schirru in an Eithne deck, makes sense". 800 scraps to get it, even had to mill a leader (Henrietta, 'cos I hate RNG) to get the additionals. I then played half a dozen games where Schirru was rendered utterly useless - Arachas, Woodland, NG hyperthin, etc. 800 scraps utterly wasted, realised the card was far too situational and you're better off just sticking with boring old Scorch.
My opinion here is you should be able to mill cards for the same, or near the same, value as buying them. That way I can chop and change my cards, keeping my interest in the game alive and also adding variety to opponents who play me.
