What is the importance of ranks
Solution 1:
When you increase the rank of a level in tiny death star all you do is upgrade the amount of stock that the level can hold.
It does not affect the ordering timing or the amount of money.
Example:
- Rank 1 = Can order 100 products
- Rank 5 = Can order 140 products
I don't find it very useful as I only upgrade ranks from VIP's but it could be great in the future.
