So, I'm in China so I realize that the challenges in the valentine's day challenges are going to be difficult. And the numbers in the three challenges 750, 850 and 1200 are ok too. But to have so many (30% 40%?) of them to be 2400, 4500 and more is just too much. Even with a full charge of energy, I can only play for maybe 3-4 minutes before I'm drained. And I would buy more of the "sale" packages, but even 10,000 energy points at $5.99 is not worth it. 10,000 will last mabe 15 seconds in a China level challenge. And while I'm at it, why is there never a blue energy container in any of the packages?
