How about when you rank up to Master, you get a Driver of your choice, under 2000 credits? I'm not doing it for my benefit, I'm saying this just as a suggestion.
Hi pie,
When you make Master, you can buy the G10 Master driver for 800 Cr.

That pretty much means a free driver, that's money from WGT's pocket right there.
Besides, players who had purchased a driver before their promotion may not feel the need to have a new one, so credits is a better payment to them.
