Are tanks overpowered?

[Bhearil]

And would be more proper to say that PLD and in a lesser manner WAR can solo(eventually) lots of content, DRK and GNB lack self healing to do so.

Heck you can say the same about RDM considering that they are THE solo job unless you receive too much damage that makes the downtime healing not worth it

Anyways, considering how low the tanks damage became in comparison with a dps job (on HW tanks could deal up to 70% of a dps, now is far lower), the only way for a tank to deal more than a dps is to either overgear them like crazy or the dps having a really bad rotation. Even healers deal more damage than tanks
