Removing Tank Stance Argument

[Seraphor]

You seem to be jaded by the terms MT and OT.

If you would read my post in its entirety, you'd see that it's more akin to one tank having a burst phase, and another having more control over defence periods.

Basically, Paladin would have a more gradual defense curve, but have DPS spikes due to its "DPS stance cooldown".
Meanwhile Dark Knight would have a more consistent DPS output, but have spikes in its defense that you'd time for tank busters.

Functionally, neither is necessarily inferior to the other with the right balance, they simply provide different play styles. One plays more like a DPS with fewer abilities required to mitigate damage, the other has a less demanding DPS rotation and has to work more at timing its defense skills.
Perhaps these roles are the wrong way around, but I've only used them as examples for the concept.
