I disagree. I discussed with rentmoney on Discord and it basically came down to this:

**Rentmoney says:** 
1. 20 cards for Champion I is just too much. Of course higher leagues should get higher rewards, but the 20:1 ratio is just too high!
2. All leagues got their rewards reduced, except for champion I!

**Pizzachain says:** 20 cards is perfectly fine for multiple reasons:
1. People who get into champion I have most definitely invested much more than the people who are in bronze league. For bronze league, all you need is a small amount of cards (the starter pack is enough), whilst you're going to need maxed/almost maxed decks to get into champion I. 
2. Bronze league isn't really a competitive league. It's more like a starter-league // a learning phase. Once you understand how the game works, you can easily get into Silver League, even with just some level 1 cards. Once you learn how to play the game well and once you've honed the right skills, you'll be able to get deep into silver and, using the reward cards you got, you can enter the gold league. 

Whilst champion I is really for the best players, using the best cards. It's really hard to get there, even for people who have a fully maxed deck. As you see in the picture below, there's really just a couple of people in Champion I:

Only 6 players are in Champion I at the moment!

So the 20:1 ratio really only counts for the extreme cases: The really good players with (close to) maxed decks vs the really bad/new players with small level 1 decks.

TL;DR -- Even with level 1 cards and not too much skills, you can easily get to silver. Champion I, however, is really only for the best few players. The 20:1 ratio is therefor a really extreme comparison between the most skillfull players with the best decks vs the worst/newest players with the worst decks.
