Which is why he isn't being put in events. People are just spending for he along with power and ignoring everything else. He's costing Oasis money. He's also pushing the little spenders, minnows, what have you away from the game because he's everywhere. It was a mistake to make him so available and now Oasis is trying to fix that; though it might be too little, too late. I think the best way to deal with what he's done in my opinion is to nerf him. People will be upset of course, they want their "I win" *on, but then those familiar with the game will manage just fine regardless.

This exactly. He was released with little consideration of how he would impact the meta and by the time it really sunk in for Oasis it was too late. The game became over saturated with him so then those in charge were left with a decision; nerf him, reduce his availability, or both. By doing the prior, people will feel slighted because they've already invested in him. Though my opinion on that is that they've likely already had their time in the sun using a ninja that's borderline broken if not outright so. If you reduce his availability, you're again upsetting people who want him because they want the same power others have or feel they have to have him to be able to compete. Either way you're going to upset a group of people and it's a no win scenario. Oasis should just bite the bullet and nerf him as well as make him more available after, but not as much as he was earlier in the aforementioned several weeks. That's my take.

Is that accurate for the next cycle?

I appreciate it, the Community Discord hasn't updated yet. As for Six Paths, it wouldn't surprise me if he comes back in the next event cycle after the upcoming one. For me at least what you're showing by itself is very appealing. Getting people to go in for Kage Madara or Edo Itachi would be a good way to drain their coupons/ingots and have them spend all over again when Six Paths shows up after.

Spenders will always have the advantage; it's what they pay for. However, I think to keep the people who can't spend money continuing to play there need to be periods of "down time" that allow the latter time to play catch up so that the gap doesn't become too overwhelming. Going back, focusing on older ninja with trials and breakthroughs is a good way to prevent that from happening. I don't feel there's been near enough of them, so we're on the same page there.

His leech would have to be reduced drastically for it to have an impact. He heals based on damage he's dealt, so of course players are just going to stack everything they have into him for damage to take advantage of it. Five percent might seem too far in comparison to twenty-five, but then I'm not sure if even that's enough.
