It is not a secret to anyone that the Bond skill of Orochimaru is much weaker than other bond skills, such as Minato Jonin, Edo Tobirama or Itachi anbu bond skill. GNW Hinata's skill is pretty good too, but It's not used obviously because there is no good teams with both GNW Hinata and KCM Naruto and using GNW Hinata without KCM Naruto when you have KCM Naruto is pretty unwise.

Back toOrochimaru Bond skill. In my opinion it's pretty good and interesting idea, but still not worth spending so much resources on it and put Orochimaru into a team instead of some good ninja.

Let's say that Bond skill is GOOD. But Orochimaru himself isn't a strong ninja. Yes, he is funny, he can do something as a full Skill Broken Sannin version at Position 1, but that's it. If Orochimaru himself would be better ninja, then he + his bond skill would worth it to put him into some top tier teams or at least medium tier teams. But for now he is a waste of slot for a good ninja in a team.

I like Orochimaru as a character. I also like an idea of his Bond skill, history of this bond skill and etc. I would like to see him more in a gaming process, to make a strong team with him and his Bond skill.

So my suggestion is not to buff Orochimaru himself, but to buff a little bit his Bond skill to make it more attractive for players. For example, to increase a duration of a barrier for 5 round / make it permanent. Or to increase % of given resistance / defence. Or to add another buff / additional effects.

I think that a lot of players like an idea of Bond skills, but not that much players have a necessary ninjas to make a bond skill. Jonin Minato, Shisui, Edo Hashi, KCM Naruto - more or less but all these ninjas are rare and not so many players have them. But everyone have Orochimaru and Sound FIve ninjas.

Everyone will win from this. Players will get a new opportunity - to spend some time and resources and get interesting and strong ninja with a new unique skill. Game will get a little bit more variety of gameplay because maybe some new meta teams will be created. Developers will get some more recharges from a players who will decide not to wait for free resources and would like to purchase it from shops.
Our moderators already said that they are an independent team so I don't see a problem for them to make something different from China ^_^

Please discuss what do you think about it. I'm very interested in your suggestions for improving Orochimaru's Bond skill.
Hope devs will note that suggestion.
