You already somewhat answered your question. Ninjas are present for people based on demand. The game is too focused on PVP and that if you don't win, your gaming experience will suffer, which is why most people will go for meta lineups.

You can't blame them for not wanting to get wins and if they think they cannot get the same results by not using meta lineups, they won't try to be creative. Don't forget that kakuzu was present every other week last year just when kakuzu was skillbroken. The demand from players has shifted to minato now there was enough time for the player base to get enough coupons to try for him just like for kakuzu.

I will bet shark kisame will be the next focus once his skillbreaks comes and people will demand for him.

You called BustCheeksDesu sensitive when he disagreed with your opnion....

Take the high road and not insult someone when they don't like what you're voicing.

All I'm saying is don't get triggered by someone who doesn't like your opinions that's all. Not very hard to do. Take that advice instead of being so defensive. You are free to just ignore it,,,,

Qv said "respect another player's opinions and ideas". Are you going to continue to think your opinion is better and ridicule someone else's opinion (which you have done around the forums) until a mod starts deleting your posts since you couldn't listen to their warning?
