The 5 sets of ninja slots for lineups is only accessible via Jonin medal, which is 50 USD. Now I can tell you safely that many people are not gona pay so much even though its a huge bargain for ingots and coupons. The solution to this would be paying a one-time 5 USD to make it accessible. OR change genin medal to 30 days and make it 5 USD or below. In this case, you will have alot of people paying for it, especially f2p.

The 5 sets of slots is very fundamental to the game and many would hope that we will be able to use it. However 50 USD is just too much. If you would make it 5 USD for a life time per character privilege, perhaps adding some other functions, you will get alot of buy-ins eventually. OR

You could make it cheap like genin medal that lasts for 30 days and many will subscribe to it. Get real, from statistics you have know that people who are f2p aren't gona use any money. But if you want to sustain or earn more money, switch to in-game functions buy-outs rather than just ingots and coupons. In this way, every new player who comes into the game can consider more options, if every player gives 5 USD for it, you can at least pay for server costs, and that is paying only for per character, you will surely get alot more money.

Anyway, I am suggesting this for your sake, since I see that you guys have really listened and removed the light at the end of the battle, I would give you guvs credit for that. But sometimes the light still goes through, I would love to see more lights being removed from the game especially like the kage's barriers. Change to dark grey or remove it. And please dont ever bring it back again..
