everyone wants Dark Knight tanks or Samurai Tanks..i'm assuming SE is not going to do either since there is so much speculation into it. There are so many other classes that can tank in the FF universe. Also Yoshi has said that the next implementation of classes will be musketeer since there is a guild in Limsa and they looking towards a rogue/thief type class since the game was released with no stealth/assassin. Which is fail since most MMOs have one at release.
