what event is Kakashi susano'o in?

Kinda dont understand why is everyone crying about ninjas releases being rushed its not like Bee or Kakashi are super important to the meta that you cant live without them. Ninjas you have in team dont mean shiet if you dont ahve the power and initiative to make them work. The only meta breaking ninja was Madara and the ppl that knew that saved and got him. Kakshi and Bee are just filler chars and youre getting them because you wanna feel a pokemon master. Not jonin menato with bond and not the Cansur Galore water main wont get any good if youre slower than the enemy so stop crying about it. If youve followed CN you know what is and what isnt meta and none of the 2 last releases were big there. Youre all just worried because you cant keep up with your pokemon addiction and when the Breakthrus of the big ninjas come you wont be able to afford them so either plan better or spend more as simple as that.
