I wont give my opinion for now but I just want to precise.
Almost all the previous rewards were good and usefull.
Leppa Berries for massive hunting, Ultra Balls for easier hunt.
Revival herbs for False Swipe training.
Rare candies cos.. I dont think I need to explain.
Master Balls for legends and a bit of money some times.
Of course Reroll Tickets to reroll legend, or to make some money.
Only the 5th day was useless.
