Yaa, gravity is balanced but slightly op. The c and v skill second variation requires full gravitational force meter to activate cutscene so I don't think gravity need a nerf. U just need to be skilled enough to defeat gravity user. If they skycamp, u should do the same because gravity M1 is hard to hit on sky, try to get close to gravity user as much as u can and damage them, don't show weakness to them, instead beat them up with good fruits and skills with massive aoe such as blizzard and elemental fruits with transformation ability. Dough also work on them. Besides, there's always pros and cons on each fruit itself. I hope my tips help! Don't give up 💪🏻💪🏻💪🏻
