Many Dragoons feel that they are left out, I thought so at first too. Especially in comparsion to st-monk. After getting better as a dragoon, I realised this was a mistake on my part. Good Monks still out-dps me, but only for 5%. Maybe 10% if the monk is really good. And I see myself more as a casual dragoon. I have seen dragoons that do insane amount of damage, there is alot of potential here. No offend but maybe you people just need more time with your class. Still, if they would leave out the positioning of HT in my opinion this would help alot.
As for ninjas dying: Since yesterday I´m lvl 50 ninja (thank you no fates anymore -.-). I´m not used to play it yet and I have to focus on my rotations. This made me die a few times in Aurum Vale at the second boss, simply because I wasn´t focused on his mechanics. What I want to say is, give the ninjas time to grow comfortable with their class and they will stop dying. As dragoon I don´t have to focus on my rotation anymore. As ninja I do.
