Tanks. But no tanks.
One thing that FFXI players have been crying out for is a new tank class. This has less to do with any dissatisfaction with the current reigning tank classes, Paladin and Ninja, and more to do with the simple logistical fact that many players have already leveled those jobs and moved on, leaving Warriors and, in some instances, Samurais to pick up the slack. But while the dev team hasn't added any new tank class (no Chocobo Knights for you!), they did state that in the upcoming patch that launches with the release of Wings of the Goddess, new job balances and tweaks -- and a major adjustment to an existing job -- will effectively render that job (I said 'existing,' so pre-WotG) a tank class. In speculating which job this would be, a number of options become possible, in theory.
