how to make more lord units?

[Falaflame]

Increasing gold rewards sounds good on paper, but in practice, it could be difficult to balance. Gauntlets would give up a shitload of money. (they already do, really, and in such a short amount of time, too)

0-map chests could have 130 base gold value
1-map chests could have 100 base gold value
2-map chests could have 70 base gold value.

But the challenge lies in balancing.
