Re: This is very irritating for me about the Manga now the war has started.
Not agreed, at least not in the way you are dramatizing it.
1: The Edo's are already dead, so it's pretty hard to kill them again.
2: Deidara, Zabuza and Haku aren't "dead", all three of them got imobilized. Ginkaku got sealed, so he could be considered "dead". The only who truly "died" was Sasori.
3: It's quite contradictory of how you're talking about Kakuzu. You first say he'sa badass and then that he struggles with some weak ninja? IMO it was the complete opposite, he was taking it easy. He was like "oh, look, I haven't seen Kinkaku like that in quite while" with a smile on his face and looking backwards while in the meantime he's killing three or four ninja's at the same time without any effort at all. It would be quite pathetic actually if he would use all his strongest jutsu's to kill all those "weak" ninja. Now he's just using his threads to kill them, which takes not much effort out of him. On top of that Kabuto is controlling him and if he would let him fire jutsu's non stop, he would destroy all the Zetsu's with the ninja's and that's not something Madara is going to be pleased about.
4: Where have you seen the 7SM struggle? They have been massacring Kakashi's division till Kakashi took down Zabuza.
5: There are a 100 000 Zetsu and 80 000 ninja. For some reason you are under the impression that all of those Zetsu's must be as strong as Zetsu (while Zetsu himself isn't even a battle type, something Madara stated himself. In terms of strength he's probably in the lower regions of Akatsuki). They are not, it are copies made of him, but of far lesser quality. Their purpose was to fight the Shinobi army in numbers. As there are more Zetsu's than shinobi, you can expect a lot of them get killed, especially because it seems they're short range fighters. Did you expected an army of 100 000 S-class Zetsu's or something? Those Zetsu are probably chunin-lvl or something. If those Zetsu truly would have been that strong, Madara wouldn't have made so much of them as he said himself he doesn't want to use too much of the Tailed Beasts chakra's. You were estimating their powers way to high.
6: There have been a lot of casualties in the Shinobi army: they have been dried, sowed together, crushed, blasted into oblivion and probably even eaten by the Zetsu's. The numbers of regular shinobi that died and the amount of Zetsu's that died are, considering that there are a lot more Zetsu's, pretty fair.
7: Yamato and Anko have been captured. Muta, the Aburame, has died. If you make those equal to Haku, Zabuza and Sasori, the only Edo's that got beaten are Sai's brother, Deidara and Ginkaku. That's still balanced out.
8: Characters like Kakuzu, Sasori and Deidara had entire arcs dedicated to them. You can't expect that they are getting again so much screetime to show off. Especially because they are a large amount of new powerful characters like the kage's and even the Jinchuriki's who haven't even been shown yet.
9: It's logical that there are always less casualties in the main good guys than bad. Especially now that they are a whole new set of powerful good guys he isn't going to kill them all off. The Edo's are damned anyway.
You overreacting too much. At this point you may say that there haven't been killed any major good guys, however the Edo's screentimes were majorly restricted from the get-go as they're already dead. On top of that the Edo's that already had a lot of screentime aren't going to be pictured as much as in the previous arcs. In the end the difference can nearly be counted on the fingers of one hand. Kishi makes most of the Edo's kill large number of ninja's, so saying that he spares the "good guys" isn't really the case. Both sides are taking casualties, not only bad guys are dying.
