truth be told, i believe copy class is the strongest style gameplay wise, being able to copy jack's limit breaker and the fist thing is incredible.
i doubt other styles could match
They kind of need it because it is the weakest style without tricks lol as the eyes are great outside fights and for copying but in a fight they are too small of a boost so they need that .Kii and Kuro are weak styles in a fight but have a lot of utility outside fighting also the cursed eyes can only copy freestyle transformations not style ones.They can copy style techs tho but those have a limit as I previously talked about and even leaving that there is a limit to how many techs you will be able to have learned at once cursed eyes increase the cap by 10 but it ain't infinite so yeah kuro needs to have those things to be competitive in a fight Mido and Aka are the top with Mido being pretty much number 1 for fighting in general and Akakiru being number 2.
Aoyu/Scared style is hybrid as it is better than kii and Kuro at fighting while being better than Mido and Aka outside fights
Even the chi type of styles kind of follow this
kii is pure Yang
Kuro is pure Yin
Both styles are bottom two for combat but outside combat they are top 2 as support or scout or other non fighting work
Aoyu is both Yin and Yang like water 50-50 so it is completely middle third best in a fight and third best outside fights
Mido is 90 percent Yang and 10 percent Yin
While Akakiru is 90 percent Yin and 10 percent Yang
These two styles are the top styles in combat but bottom two outside it tho they still have uses.
With all that said a person can be number one regardless of what style he has it's just that some styles are better than others for being strong.
Game also shows this
For example styles have inherent advantage to them
Highest power/attack is Mido and Akakiru tied at the top Mido can break and tear through empowered bones and Akakiru can cut through empowered limbs.
Then Aoyu is 3rd and kii and kuro are last.
Highest fortitude/Defense by default is Mido at number 1 and they are also the hardest to kill to the point even in death battles to choose wild Exalts out of 15-16 people fighting 3-4 survive lol because they are that hard to kill even after beating them.Mido can get regeneration as custom tech in book 2 because of Mastery on body.
Number 2 is Aoyu
KIi is 3rd here followed by Akakiru and then lastly Kuro.Tho a Akakiru could be as good as number 2 rating because their style's defence hinges a lot in skill the swordman has but without taking that skill they are 4th.
Highest agility/speed by default is Kuro at number 1(because of repulsion and attraction) without that tho it would be number 2
Mido is number 2 fastest style and without the hax of Kuro it would be number 1
Aoyu and Akakiru are the third fastest style
Kii is the slowest style.
For Soul stat
Kii is number 1 by far pure yang helps
Then mido, kuro and Aoyu kind of arguments to be number 2 because of some of the abilities or some of their composition while Akakiru doesn't have any of those arguments to be 2nd.
Now as I said outside flights it all flips and kii and Kuro become kings lol. Akakiru has their portals which is a boon outside fights but kii can do teleportation aswell with people,it can also heal the best,can fly and pretty much anything kii just needs knowledge and they can make life easier so they are best support group.
Kuro can do copying and also are best at scouting work and also finding demonic Cultivators kuro guys can track that demonic chi is just rotten kuro chi.
Aoyu can bless people,heal them not as good as Kii, help them calm down,lead people,fly,help more people lol and can gets special damage boost against Demonic cultivators.
Mido can buff allies,lead and can tame any beast and even multiple of them that said barely any mido dudes practice or use these abilities so yeah they are kind of just for show.Mido is most DBZ based style so that's why it is like that when you can fight like dbz fighters you tend to ignore the Disney princess aspect of your powers(Taming and all).
Also just for healing prowess it's like this
1.kii
2. Water
3.Aoyu
Also as for transformations the most unique one is Asura that is mido exclusive and a lost transformation to the point people don't Even know what it was except people who are old as **** or have deep knowledge you will get to know about it in late book 1 or book 2 but yeah only Mc alone is the person who has Asura transformation right now while other transformations are the stock on for their styles.
Limitbreaker is also quite unique because jack got it From someone else so there are a few people who have it but it isn't stock transformation.
