That works fine for multiple homeworlds and one champion, but multiple champions and one homeworld is still a terrible deal for the player.
Eh? Did you see the post he is referring to? Top post on page 2. The idea is to scale nebula rewards by either # of HWs or # of champions. 8 champs would get 8x reward like 8 HW.
...You're absolutely right. I somehow read that as scaling
the Nemesis response by max(homeworlds, champions). I am an idiot.
Looking at what was
actually written, that seems to be an excellent solution! Multiple homeworlds and only one champion is still a good deal for the player, but I don't think that's a major problem; and Keith was talking about boosting the Nemesis response for multiple homeworlds too, so it seems fine overall.
