Actually, Ino's telepathy is very interesting. I still don't understand why while being able to connect to thousands ppl at the same time, she can't mess her foe's mind without putting herself at risk with Shintenshin.
But if she actually learnt Shinranshin from her father, her power would get boosted by a thousand fold.
Yeah, she used Mind Destruction in a filler, but it was never confirmed in the manga, and Mind Destruction is hax as f. With Mind Transfer not much can be done in 1v1 though.
Still, Sakura proved to know well the weaknesses of Yamanaka techniques:Well, Inoichi used Shinranshin canonically, so I wouldn't be surprised if she learnt it from him.
