I found this information on the Mlife website:
We've made a good thing even better. After listening to your feedback, we are making some exciting changes to M life, effective October 1st, 2012. Here's an overview:
Beauty in simplicity.
The rolling expiration date for tiers and Tier Credits will be replaced with one set expiration date per year - October 1. If you advance to a higher tier before that date, you'll enjoy those tier benefits for at least a year!
Earn more!
The higher your tier, the more points and Express Comps you will earn at all M life destinations. We have broken it down by the percentage of Bonus Points and Express Comps you earn as you reach each new Tier Level:
• Pearl - 10% Bonus
• Gold - 20% Bonus
• Platinum - 30% Bonus
• NOIR - 40% Bonus
The offer is everything.
We've revamped the program so we can extend more compelling offers to visit your favorite M life resort. This ensures you always get the best of Las Vegas. M life is the most rewarding program in the business...
Look at this link for the program changes.
You'll still earn 10 tier credits for every base point earned at M life destinations in Las Vegas, 2 tier credits for every base point earned at Beau Rivage or Gold Strike Tunica, and 1 tier credit for every base point earned at MGM Grand Detroit.
Continue to use Express Comps at M life destinations for hotel, dining, and entertainment - or save them for an exclusive M life Moment. Express Comps earning will be limited to $5,000. NOIR members may earn up to $10,000 in Express Comps. NOIR advancement will be by invitation.
Look for more about these exciting changes in future M life communications. Thank you for being part of M life, and for giving us your valuable feedback.
NOW, I call this nickle and diming the customers. They are telling you that these changes were made to benefit the customer and they are the result of customer feedback. Now, get real!!!! Mlife is trying to sell us a story and tries to make us feel all peachy about it. I'm seriously considering to give them no play at my next visit, take all the comps they offer me and take my business elsewhere. Tell me what you think....
