I have calculated how many crystal we will be getting every months, based on regular sources. I have targeted 3 groups of players as our reference.

The three groups are:

Newbie: No WT, Reputation Level 6 Average: WT blue stage or above, Reputation Level 7–9 Advanced: WT blue stage or above, Reputation Level 10+

There are some assumptions I used in calculation:

30 days a month, always 4 weeks a month, counting two days less for weekly event per month (coz I am lazy and hate decimals)

The following table is the result.
