One point that doesn't seem to be being addressed by anyone is how this will affect bots. This change will make bots MUCH less attractive. When a ton of bots drop, rewards will go back up (somewhat) so that players not playing maxed cards won't be punished as much as it initially appears (and, of course, players playing maxed cards will make more).

I am definitely voting for this proposal even though my alt plays well above its card level and will (initially, at least) take a bit of a hit.
