I wouldn't say 100%, as they just have a higher chance of being better than f2ps. Remember there are people at a worse situation then you. I suppose you got konohamaru from arena? Some haven't. This happens in all any other games where they allow players to pay for power and those who won't have to spend their time and resources (especially the free in-game currency) wisely, and know how to play to game efficiently quickly.

On my alt account and its only 5 months old, I managed to get sailor sakura 4* and half way to 5*. Do you know how? I saved and focused coupons only on sailor. It's an dummy account so whatever on how I should use my coupons. It's only p2w if you want the ninja asap if it shown in one week. Like of course, ninjas like dpb hidan and hanzo are p2w if you want them instantly but some people save and get them.
