I think asuma's team had their moment in the war, they did pretty good but kuronai's team was neglected except Hinata she had her moment. The one that i wanted the most from was Neji, Lee, and Sakura. Neji did died like a boss but i felt he should have had more time to shine and Lee should have deffinilety been given more screem time. Sai had his moment so i think he finely developed. Sakura should have been given a more important role in the war, i know she is medical ninja and she saved several people but we know she also has mostrous strenght and she is one of the main character, as a main character she should have had a big role like save some one big, some fights and just something good from. I think kishi should have definitely given her biger role and to all konoha 12's who did not get much develpment in the shippuden after all it could be the arc.
