VIP membership is a monthly subscription planned to be priced around $10/month. It provides the following perks:
Discounts on Store items
Unique cosmetic rewards for accumulated VIP time
Other vanity rewards we might think of in the future
Additional study slots
Increased Knowledge Point gains
Wouldn't "increased knowledge point gains" be considered a pay 2 win since you'll have an advantage on the points you can attribute faster than others?
