I'm favoring 40% as my buy-in personally. I've already turned off my previous Autocash because it wasn't really doing anything special for me except for making things a little more expensive.
I definitely see your point, and I agree with it, but they seem chronically averse to making AutoCash the "best" GC payout. This might be because they see the "other" bonuses it provides, such as Club Verge access, as bonuses to that payout.
I personally think most if not all people sign up for AutoCash strictly for the GC, so I am with you there. But I am not sure they'll ever see it that way. Even with 30%, it's above average. At 25%, it IS average, so in my eyes little or no incentive to charge AutoCash rather than just waiting for a particularly juicy normal sale.
