I dont mind that Dragon has been mostly offscreened it makes sense in all other cases, when one of his top brass is kidnapped and he is doing nothing thats a big problem. The context makes him look incompetent.
He's not like Garp or Luffy who'll go in guns ablazing without a plan
He's the leader of an entire organization there's logistics and prep that would have to go into it.
He wouldn't sacrifice the life's of the many just to save one person.
And I'm certain Ginny understood that which is why she probably never called for help until after the CDs tossed her aside like yesterday's news
Is Dragon a coward for not risking his life and the life's of his subordinates to save one girl?
Or
Was he just being a good leader knowing they weren't ready for an assault on Mariejose
