You are looking at this whole matter taking for granted the event is meant for your server specifically.

If we look at the deal what we can say is that the 10k tier is meant for new servers while the 8k tier for older ones.

It's a way to balance the things.

That said the lower amount of myoboku packs there is more than twice replaced by the fact in lucky stars wheel there are myoboku grasps in the place of protection experimental vial and by the huge revamp myoboku wheel went trough (now is worth again to spend up to 35 ingots to spin it 6 times, was almost 1 year it was no more wortg it).

Anyways, that said, this fukurokumaru deal is better than the other one IF you are going exclusively for power (like i am doing) or if you want to go for one of the expensive ninjas (like sasuke rs or kakashi susano'o). Otherwise may be worse, but personally speaking i prefer this even if i would like they bring back the 5k tier in the place of the 10k, by leaving there the 8k one.

@Zathroth: edo roshi, hashirama, konan taisho and temari swimsuit aren't at all meme ninjas. Each one of them may be quite useful in specific lineups or situation.
