even though many say sasuke is top 10 tier and stuff like that (what i would not say at this moment) you can't say just because someone has some good techniques that worked on 1 or 2 people that it will work for everyone. And sasuke is not able to deal with 6pop for so many reasons:
1. linked vision = sasuke would get stomped if 6 (if not more due to summonings) enemies attack him with no chance of getting hit point blank
2. no Nin-Jutsu = many people say that sasuke has so many ninjutsu (that are actually just like narutos huge variety of rasengan, in sasukes case just many varieties of chidori or amaterasu just sayin). Because of preta path sasuke can forget any kind of ninjutsu and to defeat them one by one like naruto did in sage mode is probably not going to happen with sasuke taijutsu abilities
3. no Genjustu = due to linked vision and the fact that this will be a 6 on 1 deletes the possibility to use genjutsu for sasuke and i don't think that he is capable of such a strong genjustu like ma and pa had when jiraya fought against pein and lured one of them out of sight of the other 5.
4. summonigs = will be a huge problem for sasuke just the twin headed dog is enough for him to get his a** kicked, i mean how will he handle it i can't think of even one solution
5. and now for those of you who still say sasuke will do this and that : susano'o is made out of chakra right?.... right so have fun getting absorbed by preta path. amaterasu .... ahh the never ending black flames, well guess what they are also made out of chakra. the only way of getting rid of him is taijutsu and that is at the moment not the best feat of sasuke clearly not at this moment he is not even a threat when it comes to taijutsu we have seen so many powerful taijutsu users that his "speed" and "abilities" are no big deal
P.S. i don't want to hate on sasuke but just want to clear some stuff out
HE HAS NO CHANCE
