This days, Shisui is not viable as pos1 ninja, most of the time you will see him being used as pos2 or pos3 ninja for barrier only .. Now for the options you've given, i will pick Minato Jonin than the other one .. Im using him now and i have no problem on facing any teams around me unless power gap applies ..

Another thing, Ashura and Naruto is different person .. Calling Naruto [Sage of Six Path's] as Ashura is .......

My intend was to firstly use shisui as pos1, and then use it as support with any of these ninjas. How is it in decisive, GNW situations, when not in 1v1? Also you can get his bond only after merge, right? Since there is no other way to get kakashi. Is it still reliable without bond as pos1, comparing to sosp, sarutobi?

Hmm .. For 1v1 battles, Jminato will be better than Naruto6p or EdoHiruzen since he himself alone can deliver good amount of damage and with the likes of this matches, most likely the battles will take many rounds and im pretty sure during round 5+, Jminato already stacked up his scaling .. As for the bond, yes, Kid Kakashi will be hard to get since it is only from the Merge Event or other events which drops him, but RNG based ..

For 3v3 or GNW, Naruto6p and Edo Hiruzen are better choices at both of them deals damage to multiple ninjas .. But Edo Hiruzen relies on power .. And Minato without but, i guess he will still do go, i assume .. But he is much better with bond skills ..

Yeah, i guess i will go for Minato. Even without bond skills, stacked as pos1 he deals enough damage. Those extra 10k what would have costed Hiruzen or sosp, will just save on power, what i haven't done until now. You know how easy is to lose yourself on choices :) Thank you.

Also, so i wouldn't need to create yet another topic, can someone give tips on wind main passive skills?
I know that especially running JM together with shisui you need chakra, so i'm not sure about WM chakras passive, how much it's useful. I never used wind. Also is this lineup really best with wind? What about fire main?

Yes, better do to save for power as your next goal .. Not all the time ninja will carry you but you also needs to have power specially in terms of having your substats upgraded (initiative, injury, critical) ..

About your new topic, i have seen people using that team around my cluster, actually i made one of my member to use that team for the time being while she was getting Jonin Minato's Bond Skills .. For that wind team, kurenai with skillbreaks will be better instead of Iruka .. Positioning of ninjas will be like :

Minato - X - X
WindMain - Shisui - X
Kurenai - X - X

Skill : Impetus, ShadowClone, Shootdown Rasengan, Flower Guard, Chakra Passive and Dog of Hell summon (please double check the Chase and Summon, i think im wrong, i forgot what is it)

You c*so use fire if you want using Shield Mystery, 4th Standard or Sleep, Celestial Prison Chase, Secret Jutsu Passive, Oboro Clone with Gamaken (double check the Chase and Summon too)

Too bad i don't have all summons, and Dog of Hell is one of them. But i think +/- 2 chases doesn't do much different with other summon.
I'm also still in progress of skill breaking kurenai. That's why i thought maybe Fire with Genjutsu Mirror and iruka would be better then wind, no? Also Minato isn't Secret jutsu user, so Secret jutsu passive wouldn't work for him.
If wind is still better, should i use iruka over kurenai if she doesn't have BT yet? Or still go with kurenai?
Also with iruka, should i choose Wind Enchantment passive?

I can second Qv on JMinato choice. I would go Kurenai with his given skills even if she isn't skill broken. I'm sure it won't take too long to farm her. Also you can change ninjas formation regarding your tactics, but positioning should remain the same.
Also yes, only Shisui would gain buff from Secret Jutsu Passive, I wouldn't recommend that having Minato in line, since Shisui play more as support role.
I think Qv will answer the rest, since he's JMinato user.

I also have itachi anbu, but i think that's more for pos1 shisui lineup, right?
