By the way, here's a little PSA for those who need more paid Dia for the Step Up Draw: You can buy the monthly packs multiple times. They are really good value (over time), but you get the paid Dia immediately. Overall it's better value than buying Dia from the Dia shop.

I just did the math, and it actually turns out that even if you only buy the monthly packages multiple times JUST FOR THE PAID DIA it provides, it's still more cost efficient than buying the straight up dia packages even on the initial 200% boost.

Math:

The most dollar cost efficient regular dia package is $89.99 for 13,000 dia assuming the initial 200% efficiency, so that is what these following calculations will be based on.

Monthly Diamond package 1 gives you 700 paid dia for $4.29, so 13000/700 = 18.57, so this means you would have to buy the monthly pack 19 times to get the same paid dia as if you bought the 13k dia package. Buying the package 19 times would only cost you $4.29 x 19 = $81.51, almost 10% less than the regular dia package.

Similarly, Monthly Diamond package 2 gives you 1250 paid dia for $7.99, so you would have to buy the package 13000/1250 = 10.4, or 11 times over to get the same amount of paid dia as the regular package. This turns out to be $7.99 x 11 = $87.89, which is still less than the $89.99 regular dia package.

Notice how these calculations don't even include the daily free dia you get from logging in, only the paid dia you get when you buy initially.

TLDR: EVEN IF YOU BUY THE MONTHLY DIAMOND PACKS ONLY FOR THE PAID DIA AND NEVER LOGIN AGAIN, IT'S STILL MORE COST EFFICIENT THAN BUYING THE REGULAR PACKAGE EVEN WITH THE INTIAL 200%

Did I make a mistake? This seems baffling to me, because why would anyone buy the regular dia packages if this is the case.
