These are an insult to logic.

"Lucky Runes" In the realm of paying for power, this is possibly infinitely useless and detrimental. It's a trap for new players who may think obtaining coins is a challenge, when in fact its the most heinous pay to get something now function in the game. If you max this event for a week it wouldn't even equal the amount of coins you get daily from completing Survival Trial.

"Seal Treasure" The very first and absolutely most useless ninja recruitment method in the game. When I began I thought ninjas like Konan, Hidan, and Itachi were awesome but in fact they're quite hard to use and extremely mediocre compared to other easier to obtain ninjas. This treasure is designed to get you to waste seal scrolls when you're new on complete garbage. Every ninja in here is free through other means or 80% cheaper through other events.
