Actually I don't mind the sharingan power ups because thus far they aren't really that spectacular and they don't make you ridiculously overpowered or borderline invincible with unexplainable god like abilities like they did in the other show. It hasn't gotten ridiculous yet because we haven't seen the practical applications of EMS yet and its not like the other show where after one person gets it everyone jumps on the band wagon too.

I mean Sasuke is one of the major characters if not the most important character in the show and he doesn't have MS yet. So I don't see what the problem is its not like six or seven characters suddenly busting out MS, at worst the most we will ever see is four and its not like it makes you invincible so its no biggie.
