At this moment the most useful ones are fire and earth mains

yea, everyone in our top 20 is either using earth, wind, or fire. Will water main becomes good in future patch or that's it?

Pick a main that supports your pos 1 well. If water main gets her new skills, she'll probably become the best main.

go for fire, generally good as support. especially in pvp. earth may be for longer battles such as ninja exam.

water is not really good to keep up with anything, at least until new passive arrive, not sure.

it really depends on ur pos 1 ninja.

I'm using Sasuke Rinne Fully BT, Kisame BT, and Suigetsu. I have decent power and getting beaten by player with lower power than me because they use six paths. It's tiring.

use fire. you may want to consider replacing suigetsu with controlling ninja as support.

yeah,nowadays was naruto 6p era

water main is a great main heals and poison often times get the win plus ya can add chaos if ya want as well ...all around a solid Ninja main to use with most teams

I recommend Fire & Wind Main !!
