Should Ninja's be affected by Mass Hysteria?

So, right now, ninja’s cannot affected by the Pro-Boosted FB’s. My question is, should ninja’s be affected, or should it stay the same as it is?

Firebolt towers can kill ninjas if they hit them,  there will be no chance of them to get confused or something ?

Cannabis and Green tea

It is a professional of herbal medicine that is the same as” assassin”。。。 NinNin
