Lol this thread was entertaining but, as someone stated, look at overall game balance rather than your own selfish reasoning.

1) As far as the Itachi-swordsman argument...I guess it wouldn't matter a ton with Susano'o Itachi as he is already super armor/immune so it's rather w.e for him. However, if Edo Itachi could get root buff he would be unstoppable. He's already the best support unit in the current meta-game, no question. He has a pretty high damage standard, a mirror followed by pure ninjutsu damage reduction (team-wide by the way), chase evasion AND his mystery not only removes a ninja from the game basically but does so for 2 rounds. Why in the hell, would he need to be immune to all debuffs, and get more damage, on top of that?

2) Uchihas have never been belittled lmao. The above 2 units, both the Itachi variants, have been and will be top tier for a long while. There's also anbu Itachi who, although not broken, has a few niche teams and roles he can fill. Then you have Five Kage Madara, a great buff stripping/control/support unit. Masked man, another extremely useful pos 2 control/support. Shisui, the best passive barrier ninja in the game, barring the insane bond link barriers. Then, finally, Konoha Madara, a permanent buff and powerhouse in quite a few Konoha and Uchiha team comps. There's also 10-Tail Madara who is still pretty strong, just not insane. All in all, the Uchiha have a lot going for them.

3) The one point I can agree with is how sad Rinne-Sasuke is. He's basically unusable which is sad because some aspects of his kit are fun and practical however none of said aspects match up very well. He could definitely use a buff or a change but that just depends on what the Chinese version does with him, as we don't get version exclusives. However, if you want him to get something like dodge that's out of the question. It's a standard in the game that susano'o is a super armor passive and they have held true to that thematically. The one or two areas I could see being changed in his mystery and his ridiculously sub-par explosive mode.
