The current reward/BE system feels like a huge downgrade.
I've been keeping track of my stats so far to see how I'm doing within this new income system and these are the numbers I've gathered.
Since switching to the new BE system, I've played exactly 37 games with 29 of those being victories. That's a winrate of around 75%. I've also received 3510 BE after leveling up four times so far (3x 900 BE and 1x 810 BE from capsules). The average income per game for that would be below 100 BE despite having a far above average winrate.
Compared to the old IP model, this is simply a joke. It's almost like dedicated players get even less rewards now whereas casuals, who only play few games while receiving their first win of the day bonus, seem to have a far greater income rate per game.
