I agree vouchers are absolutely a waste. But giving vouchers a purpose while there is such limited utility for SPS would be a mistake.

"Kill off all the bots" - Yes, please, but there's no appetite for that. The new player experience is presently garbage as-is. It's bot farm account after bot farm account in what amounts to a guessing game even with superior cards due to the parity. Just be glad they are not win trading like they were doing before September 8. Spamming the same cards repeatedly is not a game, it's manual mining with extra steps. Bots are just doing it more efficiently.

Rental market is declining because of the new innovations, growing card base, and declining account base.

Most renters are bot farm accounts that turn Rewards cards around at just over burn rate. Raising rentals enriches us while eventually bleeds the farms dry or forces them to raise Rewards cards prices.

Maybe we need to rethink Ranked play altogether.
