So, now Monk/Dragoon have to compete with yet another class?

If ninja is indeed based similarly to Monks or Dragoons in terms of stats or output, I still do not think that that is enough alone to promote any kind of undue competition. If people are out playing their ninjas, then they are not playing on their monks or dragoons. It would take a significant shift in active population to shift this balance. In fact, the likelihood is for the first couple months it will be ninja overkill - ninjas competing with ninjas. As it stands the Duty Finder functions by role not class, so once you are actually in the duty you're still competing potentially with the same number of players regardless what DoW dps role you happen to be playing at the time.
