Its good that you ask me that..
I myself wont ever use genjutsu in my life.. Because I hate them..
I have also no knowledge on genjutsu, you have to ask that to sensei..
But, dont add a genjutsu to the combinations I give you..
Basically I want my aprentices to fight like me..
Thats my goal..
And if you use genjutsu, that wont happen.. In my opinion its like this..
If your opponent uses genjutsu, then you can to..
If your opponent doesnt.. Then its not fair to use genjutsu, you know?
