In this version it will never be free overtime because they keep changing events and removing ninja..for example cursed hidan removed from luckyboard etc but in china they have given out edo hiruzen every 2 weeks for the past 6 months+

I think the game gives plenty of free coupons to help contribute to F2P gaining the P2W ninjas, it's a long game sure but in the end you're still going to get what the P2W have. As a F2P you really have to practice patience with this game.

actually u mean increase price of most ninjas since that was the case for the most part , rarely have we seen a reduction in price for most of them ( closest example that comes to mind was Rasa - anniversary event 80 fragments total cost 8800 cp / ingots , last event he was in total cost for 80 fragments - 14600 cp / ingots , also sailor sakura usually at 3200 cp / ingots , last event she was on sale at 5600 cp / ingots )

The game in general is overpriced. As OP said I understand the game has to make money but the pricing is greedy, especially when you compare us to across the pond. I maintain that if the pricing of everything was halved they would make more more because recharging would make more sense. I can't tell you how many times I was going to recharge and then decided against it because "its not enough money to make a difference" anyway.

The way the pricing in this game is designed currently "milk every possible cent out of those that do recharge" instead of trying to encourage people that don't recharge often or don't recharge at all to do so. There is no incentive to recharge when if you want it to make a real difference you need to recharge $1000 or more.
