Doffy should've atleast been worth 800-900 mill if he was unfrozen. Yet Luffy got a little increase. Bounties have nothing to do with being frozen like that bozo said. Croc would be way higher if he was unfrozen. Didnt stop Luffy from only getting 100 mill.
Considering how the fight went down.
Law got 1 hit, but during the fight, you had an entire town chanting Luffy's name to beat Doflamingo. Since they found out he was Luccy, they should realized he also beat Chinjao.
These 2 things combined should NOT have given him a mere 500M bounty.
Maybe Oda did it to make the jump towards 1.5B more "surprising", since it would be too obvious if Luffy went to WCI with a bounty already close to 1B. Who knows.
It's BS.
