Oda's scaling is on point.
- Law and Kid defeated full health BM, 50% of taking down an emperor goes to each.
- Luffy defeated, and let's be generous, Kaido who also around 50% after his gauntlet.
Everyone getting the same bounty is fitting, now factoring in God fruit Nika and Luffy basically being the leader of the alliance then i get why people want him to be higher.
I think he should be higher.
Edit: Not like Law's fruit is any less meaningful than Luffy's.
