Everyone is but Ida should take as many breaks as he needs, even a month or to if needs be. I want him to finish his masterpiece, and enjoy well due retirement, unlike kentaro miura (berserk). Fans needs to be more patient and show care towards oda. The blame goes also to his editor, they need to make him take more pause. Like 2 chapters a month, once every two weeks. That's still 2.5 tomes a year.
Yes you're right, let the writer get another burnout and risking not finishing One Piece to the end cos he dies of stress and fatigue. The level of entitlement of readers is Insane. Oda doesn't owe you shit. You probably read for free anyway.
There's no way loki joins the crew. He'll eventually rule elbaf just like momonosuke did. Plus, as the crew said, he's too big for the ship. Another argument that goes against it is that he's too strong, and Oda said multiple time that no one will challenge Zoro and Sanji in terms of strength as number 2 and 3 of the crew. They will be allies for sure, but nothing else.
