There is so much speculation in the General Discussion forum about possible new classes/jobs, such as Musketeers (which Yoshi has indicated is certain to come), Dark Knights, some thief-like class, etc. But when SE starts adding new classes/jobs, must they also bring online new tanking roles?

I wonder about this because while there are many different ways of dealing damage, there are only a few proven ways of tanking. You generally either mitigate the damage (PLD) or you self-heal/evade (WAR), though of course each tank type is not absolute. Warriors do mitigate and Paladins do evade/parry. Still, if SE plans to bring on new classes that are DDs, support, sneaky classes, whatever, for balance's sake -- given the already existing imbalance between damage dealers and tanks and healers -- does that mean they need to bring into the game more tanks (and possibly healers) as well?

The problem with more tank classes is that it is just awfully hard to balance them so that they are all equally desirable. Just wondering.
