Great guide, keep up the good work. looking forward to more on this for high level builds as well.
There are 2 things I would like to mention here-

1) Gaara is totally worth it, even more so for wind main. For nine tail event, every class need a barrier ninja that boost a certain type, Gaara does that for wind main.

2) From the start, save every single seal scroll you get until you reach level 70 and unlock sage treasure. Don't spend any of them on seal or tendo treasure. From sage treasure, you can sage naruto from anywhere between 20 - 150 scrolls. He's a favourite choice for every class and even more for wind class. You c*so get Ao and traitor Orochimaru and both of them are very useful. So save up from before and when you unlock sage treasure at level 70, wait for a seal rebate event use all of them there.

Hope it helps.
