Xeno believes paladin should NEVER be main tank

I would say Xeno is very correct. It comes down to simple math, the WAR/DRK loses relatively little DPS when in the MT role vs their OT potential, however, the PLD loses an insane amount of DPS when forced to MT. The fact comes down to the PLD pretty much needs to be in Shield to MT effectively because of the required emnity modifier to maintain hate, the lack of fluid stance switch also hinders the ability fine grain the dance like DRK/WAR.
The reason the PLD is in this awkward position is because the DRK/WAR have sufficient mitigation to go through most fights rendering the additional mitigation afforded by the PLD to be relatively worthless.

Until they start designing fights again where the extra mitigation and strong Physical blocking can make the difference on clearability, PLD is more valuable in OT.

Anecdotally, my group used the PLD in mostly OT capacity in A3S + A4S and the extra DPS the PLD can churn out in Sword is impressive and actually completely outweighed the amount our WAR loses when in MT.
