Chrisbox, I can see where you're coming from, in stating that prior to the release information about the Rogue/Ninja classes, by Yugiri stating that she would teach the Eorzeans her techniques, meant that a new class would be introduced - which aligns with the way she battled the enemies in the Sapsa Spawning Ground.

At least, that's what I am getting from your post. Basically, if you played the 2.2 patch all the way to the end, it's hinted that Rogue would be the next class. Because, Yugiri is clearly not a Thief. :P

Uriel, there's no need to be rude to someone who's excited about something they picked up on in the story dialogue.
