Luffy getting 3 billion is fine, but Law and Kidd both getting 3 billion, too, is just complete nonsense.
Nothing in the story justifies that. Heck, not even anything the marines know from a story standpoint (inner-manga logic) justifies that and Law is one of my favorite characters btw.
To then somehow make Luffy an emperor and the other two not, while they actually gave all of them the same bounty (mind you: bounty = threat level according to the lore) is just another questionable decision.
