Ok so I'm not sure how this really (really) helps the new players move up. Sure you've sorted the CP problem, but the smart money is always gonna rent useful cards while they increase their CP.

The problem is now they are getting junk cards (until there is none left) then the 'machine' start consuming good cards that the altruistic people might have listed cheaply so other may move up ranks in an economical way. (Yes I still want to believe these people exist)

So are we teaching people anything? Are we educating them to understand that 'this card' + 'this card' will help them to rank up and provide CP at the same time?

It's an interesting feature, but I still need to be sold on the benefits.

Let's see how this plays out. And as a renter I feel it's prudent to not enter the free for all until the bid price is about what I want to let my cards rent for.
(Of course, this is good for me and not so much for the players, especially if the other renters are sitting on the edge and waiting to jump in too)

I hope the launch goes well. RIP your RC. :)
