I think it'd be cool if she got MS..
I'm curious as to how they'll keep her from going blind after gaining it because it's a doujutsu that's destined to lead the user to blindness without the proper means..
Pure blood Uchiha had issues with the eye so I'm kinda on the fence as to what her special ability could be..
I've heard from alot of fans that won't be happy if she get better techniques then the likes of pure bloods like Itachi Obito Shisui Madara & Sasuke with her Haruno bloodline but I also see Uchiha fans come to the defense of Sakura because of Sarada & Sassuke so their hopes are high..
It'd be silly for the creators if they didn't give her MS cause it's been a big part of the series..
If your going to milk the cow, then it's best to get all the milk you can an given her the eye would milk the cow dry..
