Sasuke is great, you only need to know how to use him.
Try him with Rin, or with Konan Swimsuit for example. With lightning, earth or fire main to generate chakra for him.
He's a beast, to even compare him with Sasuke Susanoo shows a big ignorance about the game or just a desperate attempt to get him buffed.
S.Susanoo can't be better than Rinne because he was released years before him, i'm not even going to bother putting both BT together here to refute your statement, unless you keep insisting on the matter that is.

That he was was suppossed to rival Six Path Naruto ingame is not only false, it's also been denied multiple times. Just as X stated we have already so many posts with this topic usually with the same people complaining and it gets tiring, something should be done against repetitive topics that have already been closed. You have been told NO, because the ninja is balanced properly and there's not a real reason to improve him.

You know what you could actually complain about? About Six Path Naruto himself, and there you'd find a ton of support. Because that ninja yes that is completely unbalanced. We've told many different ways to nerf Naruto and nothing has been done, instead of buffing another ninja to God category just balance the single ninja that has ruined this game.

There's nothing unfair about closing topics that already have been discussed frenquently to prevent the forum to have the same thing explained a trillion times.
"he isn't even near naruto 6p"
Yeah don't worry, no ninja is close to naruto six path, i've seen fights in bonds where a player with 10T Obito would struggle against a 6p Naruto with about 200k difference, that is ridiculous. Again, instead of buffing everyone just nerf one ninja.

"sasuke only has super armor"
He also has an inmunity overruning fear passive that no other ninja has. And if you manage to end the round with 40 chakra, something incredibly easy, you're getting +60% Ninjutsu. In order to get +60% Ninjutsu the 6p Naruto needs to attack you 4 times. Some would call that an advantage over 6p.

"making him inmune to damage won't make him unbalanced"
Uuuhhh... the day after you'd give him this buff he'd become core ninja in every team. How do you kill a ninja that prevents you from doing standard attacks and recieves no damage? No thank you. 6p standard and mystery are unmissable my friend, so giving Sasuke a chance to evade damage is equal to making him stronger vs anyone but the ninja you're complaining you're no rival for. lmao.

I already know about Ibiki, I do have him so yeah I don't see how that makes me any *, what is your point? Does every player need to use Ibiki in order to have a chance vs 6p? What do you even mean.
It doesn't matter a ninja is strong in the anime and less strong in the game, we have a lot of cases where that applies, not only rinne Sasuke, yet you only find a noisy few spamming about Sasuke.

"he's suppossed to be one of the lead characters"
How many times does this need to be explained to you? STRONG IN ANIME DOESNT MEAN STRONG IN GAME.
The developers are not forced at all to deliver a godlike version of Sasuke, the sooner you accept it the happier you'll be.
You could use Kabuto Sage as you said, you could use Creation Kakuzu, you could use Byakugou Tsunade, you could use so many things and that's the fun part of the game, mate. Think! Not expect a single ninja doing everything for you, make a lineup to make your Sasuke unstoppable, there are many ways of making it.

I haven't been around since 2019 my friend that's the time I started posting. I'm in the game since version 1.0 not even the UK servers, then i migrated here due to content reasons. I post as much since then because I care of the game after I've been so many years here, of course I want to see it heading in the right direction, and that's definetely not adding more godlike ninjas. That's precisely what has made quit veteran players, the boredom of seeing people expecting to have a single ninja doing everything for them instead of building diverse fun teams which is the main point of the game by the way.

"Nerfed" is the word you're looking for. I guess being on mobile makes it more comfortable to write u instead of e.
You know what i would support? A new Sasuke. Make a new Sasuke with the survivavility you're asking for, but Rinne has sense in his skillset and as i told you: giving him the chance of evading damage doesn't make him able to compete with 6p with is what you were complaining about in the first place, just makes him a pain to deal with to every other ninja.
