I'm currently using a Main, Kakashi, Hinata and GNW Kiba line up and it's working wonders in the Ranking Battle! I swear even though I'm just level 58, I can beat level 64 and higher!
GNW Kiba is truly one of the best characters you need to have in your line up as an Azure Fang. :)

My lineup is this:

Main -- Kakashi -- Hinata
x -- GNW Kiba -- x
x -- x -- x

My talents are: 3--1--3--2--2
My summon: Ninja Cat

You should try it. :)

Is that so? Then I apologize for any mishaps I had committed.
But, I'm just wondering, what do you mean by 2.0 update?

Ohh I see. Thank you for the information. :)
