Question about RCs and earning tier points. Dan:

When you earn 5,000 tier points on your way to earn 7 Stars you also get 5,000 reward credits.

5,000 reward credits is worth $50 and not $500 as you wrote above.

Regarding being overcomped the real question is this:

Do you have a profit playing casino games? If you do you can be overcomped. If you lose money in the casino then only a true and honest accounting will determine if all those comps erase what you lost.

Being overcomped by $5,000 worth of comps is meaningless if you lost $5,001 of real money.

That's really the bottom line for everyone.
