People still have not realized that Summons act like a army. Edo Army is to Kabuto as the shinobi alliance is to the Kages.
Edo tensei being your power doesn't = The shinobi themselves being your power. If you want to include them as the person's power, than give the opposition his army of people that he is possibly leading. Because in the end Edo tensei user like Kabuto/Orochimaru is simply leading dead people.. While someone like Madara and Hashirama or a Hokage would be leading Living people.. and funny thing is they will all be under their power.
People of the village are under the Kage's control.
People saying "summoning is a summoning".. we know summoning is a summoning.. however you believe that an another individual with his own powers is somehow the power of another individual with his own powers.
Because with that logic Frog sage MA > Naruto, why? She can summon 4 frogs + Naruto. While Naruto can't summon that many.
You got a good point. However,..
How about we restrict it to 1 v 1 with Jutsu only?
Then, will the Kages be able to command their army?
What if the a Kage ends up in a one v one fight where much of their army if off in another location? This has happen plenty of times in the manga. Hashi vs Madara, Oro vs Sarutobi, Oro vs 4th Kazakage, Sasori vs 3rd Kazakage, Gaara vs 4th Kazakage, Gaara vs Deidara, Danzo vs Sasuke, Ay vs Sasuke. So, so many examples of where a Kage is forced to hold their own weight in a 1 v 1 fight.
It is a common occurence to have a Kage fight and no have the immediate covenience of their entire army with them. However, if Kabuto ends up in this situation, he can just summon all the edos at once. What will the Kages do, blow a whistle and hope the their army can instantly appear? You see the difference?
