I understand that you need to take steps to control the economy.
I don't feel constantly reducing the rewards for low level players is the right approach.
Especially when higher tier players get exponentially more rewards.

I really wish you'd take steps to encourage players to grow as opposed to throwing hurdles at them.
For instance, when you gave EVERYONE access to cards even if they didn't own them that was GREAT.
It shouldn't be hard to build on that.
If you are going to reduce DEC rewards, instead give low level players account bound cards so they can power up and move to higher tiers. You can even cap how high the account bound cards can be leveled to minimize impact on the market.
And get rid of the potions from the rewards for the lower leagues... If you are a bronze player, or even a tier 1 silver player, you are never going to use even a fraction of the potions you get....

But anyways, good luck... I'm on a splinterlands vacation so I'll check back in a few months.
