Nope, and while I've been scolded because of using the "G" word that rhymes with Weeds, they aren't about to be Penny Saver ish with us. I mean, look at how they handled the first limited time treasure, they combined two treasures into one, ruined the alternating rares, and removed the ONE RARE (mei) that people actually wanted.

Don't even get me started about the 4 star nonsense for the super rares for breakthrough books. As if those fragments fall from the sky.

For the OP, Never do beyond 300 for a rebate at this juncture. The reason why I say this is because based on math, its never a good deal to go to the 500 or 800 slot. You could instead do 3 full 300 rebates with the same amount of scrolls. You will get an extra 198 seal scrolls from those 3 rebates (66 seal scolls per rebate). That is 200 more seal scroll pull progress. When you think about it in numbers, the 800 mile stone is just pure garbo.
