Can't believe how many people are happy with Garling L here. You should be mad.
You have a fb with dead guys or retired ones that serves not purpose for the future of the story, except for Imu and Garling.
So yeah, Rocks was this dude, but what we gain with Rocks/Harald/Roger/Whitebeard/Kaido/Rayleigh/Garp's greatness when those are dead or retired?
Now you are stuck for the next 10 year with the Holy Roppos and Gorosei and people are happy they are fodders?
