Since getting my Ninja maxed out to Level 50 and noticing other Ninjas in dungeons doing Ninjitsu, there has been the use of one Ninjitsu in particular and it is never used correctly or effectively.
The Ninjitsu in question is Doton which is used to create a circle that causes the Heavy status affliction on any enemy within the circle. However, I have noticed a lot of negative consistency with it. When I try to use it, the tank pulls the enemies out of the circle, rendering the Ninjitsu useless. And when I see other Ninjas using it, they use it against bosses, thinking that bosses are susceptible to Heavy. But having also played as a White Mage and the Stone ability also causes Heavy, I know for a fact that the bosses are not affected by it.
So tanks, let us use our Ninjitsu effectively and my fellow Ninjas, use your Ninjitsu correctly please. We are trying to help each other after all.
