Luffy... the only character in series to run out of haki.... Oda just LOVES to restrict Luffy...
Katakuri was spamming future sight for 11 hours... he never did an attack without future sight through all 11 hours, yet NEVER ran out of his continuous use of haki...
Every power Oda gives Luffy HAS to have drawbacks... yet every enemy he faces, never faces drawbacks... you can give that enemy god-like power up and STILL wouldn't have drawbacks....
Doflamingo for example,
Turned an entire city into threads with awakening.... WHILE he was fighting Luffy + Birdcage was moving automatically, and Parasite was activated on some and they were restrained by other people... just wrap your head about this and try to make sense of this multitasking which makes ZERO SENSE... yet NO DRAWBACK LOL
Luffy coats haki 2/3 of his body and 5 minutes and he runs out against Doffy LOL
The epitome of bullshit
