So I noticed under all the other achievements our ladies win something permanent at level 5. But with great challenger and high fashion it goes from winning 2 x10 energy packs at level 4 (valued 60 diamonds), to winning one +3 energy for 14 days (valued 10 diamonds).
How does this even make sense? Especially given that the tier 5 reward is worth 50 diamonds less than the tier 4 reward. Going by the theme of having a permanent reward at level 5, why not have a +1 or +2 to energy permanently?
