From dps to healer or tank?

[SpiritMuse]

I'd have to disagree with this. SCH is actually, by far, the easiest healer to use in the game if you are just learning the ropes. Yes, you have to use CNJ until level 15 anyway, but a SCH is far more lenient with its DPS and healing because of the fairy. So if you are coming from a DPS I would think that the most logical next step, if you want to transition to another role, would be SCH. In the early parts of the game it mostly functions as a DPS who can heal.

CNJ/WHM is the most straightforward healer though. It's just powerful healing with no extra stuff like pet management or various different rng-dependent buffs.
