Still makes me laugh whenever I read a post about a dragoon and his wyvern, it's like all the people in this game that play dragoons don't realize that dragoons and dragons are enemies, dragoon's skills aren't there to control or link with dragons, they are skills used to kill dragons.
If you read the description of the job http://na.finalfantasyxiv.com/pr/game/#!/jobs/content you would realize that it would make no sense lorewise that dragoons team up with dragons.
