Mayaki Kekkei Commotion Solution:

Okay. Theres been some commotion on the kekkei-genkai of Mayaki's clan; Rami. Now, the Rami were Master Genjutsu users, who were even more advanced then Uchiha. The problem is, her Kekkei doesnt have a side effect for having no hand sign usage after casting Genjutsu.

My effects are:
If she uses 5 or more Genjutsu without having to perform handseals she will suffer from temporary blindness that will last a week (REAL LIFE WEEK).
If she chooses to temporarily disable her kekkei and perform handseals to use Genjutsu there will be a minor infraction on her blindness because her Genjutsu is so powerful. If she uses 8 Genjutsu she will suffer from blindness for a whole Real Life day (24 hours). Once it is up, she can continue to do it.

Mayaki, I know this is somewhat unfair - But yeah, look at it this way. If you are blind for a long period of time you will develop increased senses like feeling vibrations, and depending on sound movements to predict where your opponent will be. Not only that, but using it this way will highly develop your Taijutsu skills as well as your predictability.
