Each time the Straw Hats adventure in a new island and country there is one or several big issues in the place in question : in Alabasta they had to deal with a rebellion and Crocodile's plot, in Skypeia there was a tyrant who wanted to detroy the country, in Water Seven there was a plot against Iceburg and to capture Robin and Franky for the WG, in Saobody it was the problem of slavery and the tyranny of the Celestial Dragons, Dressrosa had a tyrant in Doflamingo,etc...
If the Straw Hats go to Elbaf as many have predicted and hoped for a lont time, what kind of problems could there be in the country of giants ?
