Xeno believes paladin should NEVER be main tank

[Reynhart]

And yes, no damage penalty would be demonstrably not broken at all based on PLD MT numbers compared to DRK and WAR.

Not broken, yes, but it would feel kind of weird for PLD to be the only tank without a damage penalty.

And I still feel that simply increasing PLD's damage is not a viable solution in the long run. Comes the next expansion, we'll probably have a 4th tank. In the end, if they do around the same damage and have the same mitigation, they'd mostly feel the same. DRK and PLD are already copy/pasted on most of their skills and even WAR is not that different. Each tank should have something really unique to bring to the party.
Since I doubt the meta will change for "moar DPS" it means that each one should increase the raid DPS in some way. And true to its name, WAR's way will be by having higher personal DPS.
