...there are only 84 days between HoT and VoA unlock. I know there is a lot of vagueness around 3 months for expansions, but the general view is 3 months is 90 days. We're getting short changed a week! Oh, and please make more keys available for expansions going forward. Adding the small amount you did was not enough. Thanks.
This is precisely why they advertise in number of weeks, not number of months. 7 Days per week 12 weeks per level cap raising expansion (after GoD launch) 8 weeks per non level cap raising expansion (after GoD launch) 7*12 = .... 84! 7*8 = 56 Those are your unlock number of day variables. Nothing is getting short changed, and there is no vagueness.
Ah hah! You forgot to factor in the rotation of the Earth slowing by an average of 2.3 milliseconds per century, you fool!
It's been this way as long as Phinigel has existed... 84 days is standard and what you've gotten every single time for a "3 month" expansion.
