I was thinking about this a lot whenever I died when I just started playing the game, but recently I've realized we are Demigods and killing one surely isn't easy (or, at least, it shouldn't be, unless played by a clueless one) and should be rewarded properly.
All Demigods are strong. They are not built to die easily. By having a lot of reckless players, there are far more kills in game than I'd ever expect. (We were all newbies at one point.)
From my point of view, this game is about playing carefully - advancing slowly, being careful not to make a mistake and trying to exploit others' weaknesses. When I play against such players, kills are rare, unless one team is pushing real hard. And when does one team push really hard while being successful at the same time? When their team strategy is better in given match.
So, in matches with skillful players, kills are hard to get and they should be rewarded accordingly.
My whole theory is based around fact that, if played carefully, there won't be too much gold in a match from killing other Demigods (until one team is clearly winning, when it's too late for that gold to change anything).
Of course, more often than not, people don't play carefully.
Due to that, I would support getting just a little bit less gold during first couple of levels.
What worries me more is illogical base stats distribution for Demigods. Like, Rook having less armour than Regulus (!) and almost twice as low as Beast's. Just to mention that one. (Some damage and health distribution among Demigods doesn't make sense either.) I'd love that to be fixed first.
Then we can talk about the rest.
Still, I'd like to say the game is more than satisfying. It's great.
