I see a lot of hate towards players who want events that don't invlove coupons/ingots. Now I'm sure most players don't just want things given to them, but rather have the chance to earn them. Like imagine a SA like event where you have to go through x number of rounds, and if you beat it you get the ninja, or other rewards based on how you did. That is just an example, don't take it as what I want in the game. I was just trying to throw the idea around of more chances to earn things, instead of just buying them.
Also for people that say you can save coupons for events so you don't have to buy anythings. Yea I know that you can, but the time you have to save for is a bit ridiculous (at a rate of 50 coupons/day to get jiraiya in the birthday event would take about 6 months).
