What I want the most in Rell seas is that you can infuse you devil fruit powers into weapons and fighting styles if you can't already. A bit like whitebeard's move where he uses his sword to use his devil fruit abilities. Idk if that's in but it would be cool to add if it's not. Also using haki with devil fruit abilities should be a thing. But it would make less sense so I prefer the first thing.
Those fruits are sick but I'm still no matter what going for a zoan type, I just love the hybrid forms (I really want falcon or wolf). W vid btw love your content
Also I hope they add meito. Like the really strong weapons. For example there could be normal weapons, and then higher grade weapons which get rarer and stronger the higher grade it is. As well as stronger meito should be able to be used in compability with devil fruit powers and make it stronger with the higher grade.
