OR if paladins are supposed to be the most dps of all tanks it could be made so that they do not take an aux penalty beyond the first mob or two, in other words they deal as much dps if they are tanking 1 mob or 6, not making them better tanks per se but making them better suited to their role of fighting multiple mobs at once.
I think we already have enough bad stances, we really need a non /s 3 tanking stance. I do like the more mobs better tank stance idea though.
