Luffy vs Lucci is crossing into filler territory
Lucci just donutted Sentomaru and yet Luffy still isn't using ACoC. Why? I get last chapter, Oda showing off Lucci's awakening to show that he's strong, having the two rematch.
But if Luffy is still yet to use ACoC this chapter and Lucci still isn't defeated, this fight is filler imo.
