Personally I've been thinking about trying ninja in the future after finally catching up with the story and such as a WHM (took a loooong break from the game), but now that they're going to be positional based idunno if I'm any more tempted to play them than I would a monk. I mean they're both fast attacking melee dps with cool glamours and small weapons. To me, it was the lack of the positioning requirements that made ninja stand out. Though I haven't gotten around to reading up on their lore.
