Temporary HP Tank

[ZenBear]

I mentioned this once before as a possible change to the Warrior self-healing mechanic as a way to relieve some of the healer stress of seeing a Warrior's health drop like a rock after every big hit. The premise is that by having Warriors build "shields" of temporary HP with their self-heal abilities allows for a more proactive and preemptive playstyle. Instead of taking a big hit that drops you to 25% health and popping Inner Beast to heal back up while the White Mage frantically casts their biggest cures, the Warrior can pop Inner Beast before the attack to generate their shield which will soak up most of the damage and leave you at 75-50% hp.

My suggestion received a largely negative response without any explanation of why other than a single reference to Death Knights from WoW. I have no experience with DK so I don't know what they were like or why their form of temp hp generation was over/underpowered or what.

Does anybody agree that this could be a good idea? It's never going to happen, SqEnix has already decided how WARs work (though 2.1 seems on the verge of dangerously homogenizing WAR/PLD), but I still think it's a good idea. If you disagree, please explain why in greater detail than "No, you're an idiot."
