i like people asking for a nerf for a class they haven't try... if you had try the ninja, you will know that ask for positional in the combo will have make it unplayable for most of the playerbase...
the ninja is right where it must be, in pvp people don't had time to really understand how work the jobs or how beat it.

i don't think dragoon need anything else than increase the M.def. the jobs is quite easy to play in comparaison of monk and ninja, sorry, but if the jobs was more powerfull, why bring monk and ninja that need more work for be mastered?

seriously, people need to try to nerf other jobs and simply enjoy the fact that we have more choice for create our group.
