who have said flashy stuff?
add a skill with the same function will have no interest. and if they want to make us a support melee, ok, then do it well. use ninjutsu for do this, like add debuff that will give synergy to the group.

it was possible to make tons of stuff, want a few example?
- a ninjutsu that will the target with a debuff after deal damage, this debuff boost the people attacking the monster increasing them cast/skill speed.
- a ninjutsu skill that allows to gain effect similar to the elemental wheel. each element giving a boost to a type of elemental damage. suiton, boosting the next thunder spell casted on, hyoton increasing fire,...

you can even think at some buff for the ninja, like:
- a kage-bushin, but instead to protect the ninja, allows him to get the same effect than oath of sword for a short period.
- allows to cast a Short duration AoE huton, that increase speed of attack of the whole group in the area.

and even some that have function different than what we have so far:
- a ninjutsu that allows to switch place with a team member. can be exellent when the healer is target and for give him some room.
- a kage-bushin that can be cast on a party member only that will absorb one attack.
- a ninjutsu allowing us to be teleported behind the target of a team member.

i dunno, i'm sure, i'm not the only one that did think to different ninjutsu that have different function that can be added? but most important was maybe to add the ninjutsu as a part of the weaponskill system. make the two system work together, not against each other. my main grips against ninjutsu, is the shared CD of 20 second, we are the only jobs that can only use our symbolic skill every 20 second. a dragoon if he want can simply do him 3 jump in row, is stupid i know but it's still possible. why not have give the cd to each ninjutsu skill? like Raiton do have 20 second CD, etc... it will have give more flexibility to the ninja.
but more important it will be able to add ninjutsu skill with less cd, allowing them to be added into combo.

i dunno, i'm only trying to think what it's possible or not, this jobs have soo much potential and for now... it's clearly unexploited. because soo far, with positional, we aren't really different of the dragoon or monk... (depending of the number of skill with positional) the only difference is the mudra lag, every 20 seconds.

why play ninja over dragoon or monk? what we had soo far was 3 jobs with different gameplay, but with positional and the ninjutsu underused, we aren't different of the dragoon or monk. before it was, if you want an heavy positional class, you go with monk. a job with a bit of positional, you will go with dragoon. and if you want a jobs without positional, it was ninja. it was the difference between the 3. no?
