as itachi said each jutsu has a weakness,and i think i found susanoo's:
if you're a susanoo user,you can't repair susanoo if it's broken,actually you have to drop it to use it again in full size,and if you reached lets say "only ribs" stage of susanoo and it's broken you can't go any further unless you drop it then activate it.
i noticed this while seeing madara vs kages fight,madara never actually repaired his susanoo not even once,and he dropped his susanoo a lot of times,that may also mean that you can't maintain it for a long time you have to use it in seperate periods of time(thought i doubt that)
so your thoughts on my theory?
