Make default jumps higher as the player‘s doriki increases. There are many examples of strong characters in one piece jumping insanely high without using geppo or what not:
-Aokiji in marineford as he approached the tsunami whitebeard sent
-Kaido and Luffy basically went flying in Onigashima. Well default flying should obviously never be a thing in the mod.
-Scabbards also jumped really high while fighting
- Zoro approached Alber using jumps despite him standing literally flying in the air
- Garp jumped up to Kuzan effortlessly before using blue hole
- I noticed that in some of previous examples there was some kind of short floating going on, though I‘d take that with a grain of salt.
Saying that these were exceptions is a headcannon. There are way more examples which I‘m not bothering to mention.
Personally, I don’t see it making sense that a literal monster with max doriki can only do vanilla scaled jumps. Top tiers (max doriki) should be able to jump really high without having to use geppo. Just like in the original series. You can add a cooldown for that if you wish, but you get the idea.
