In all this, there's a solution that I keep seeing get overlooked, WHMs can DD too, bring 2 for safety let em spam nukes while a PLD heals, they still shouldn't pull hate ever as long as they actually let the PLD cast a succor or 2 for effect. Your pts ttl dps will more than outweigh a WAR tanking in the boss one on one fights.

The one problem I encounter on PLD, is that WHMs are a little to quick on the cure trigger so my succors end up being wastedish landing for 3~400 instead of 1k. Course after the long period of WAR tanking so cures had to be tossed fast it's become habit for many to just keep the tank @100% even if it's not the most efficient use of MP.

In hi mob count areas WAR will still reign because Rampage will stay capped and SC will continue to rape weaker mobs. With a reasonable crit rate to boot heals become almost unnecessary so WHM can go DD happy.
