Kimono Itachi was made to "maybe" face new meta teams i mean Kakuzu and Sosp , his myst can increas cd by 2 , its beautiful to see Sosp has 3 cd xD
and if barrier is active you cant use Standar attacks when u have + 50 chakra , witch is the case for Kakuzu teams... it relay on chakra buff ..

anyway i still Think M5K is the best ninja in the game for me cauz im running debuff teams , his barrier take off immunity , buffs and barriers , and prevent myst and gives u time to think about the strategie xD , dnt forget about the chase that does crazy damage drain 40 chakra ....ect

so botom line is any exclusiv ninja is good if u know how to choose the right team
