I have the world mastercard for sometime now but have not been using it. The reward program seems quite good if can get the 5x/8x reward points. However my concern has been the following
1. have to remember which shopping centers qualify for 5xs reward.
2. the is another long list of which merchants in the shopping center actually give out those 5x points
3. limit of 9000 reward points a month (ie RM1800 for 5xs, and RM1100 for 8xs)
4. 1 billion reward points per year

Does anyone actually use this card and memorize the conditions?
Is there anyway to quickly check if a particular outlet qualifies for condition 1& 2?
Is there a prompt to tell you that you are no longer qualified to get the 5xs/8xs rewards? (hopeful thinking, I guess)
Is there a prompt to tell you that the 1 billion points have already been reached?
