IDK where you're getting your calculations, but a 20% increase in your defense is not 5~6% reduction in damage. In fact the real reduction changes with gear, so already, you've popped a hole in your own statement. The more defense you have base, the higher the amount increased is.
Did you not notice my point was against packs of mobs? No shit Bloodbath isn't going to do as much healing with only one target, never said it would.
Didn't say I used it for threat, I said I used it for certain boss mechanics. Wild Charge + Crackle Hiss in T10, Giant Bavarois when he starts to chase down a party members for Flail. Of course Hallowed Ground is flat out better, never said it wasn't a great skill. However, compare it to the cooldown on Holmgang as well. I am usually able to eat four or five wild charges + Crackle Hiss in T10 because the cooldown is short enough. Each has their up sides and down sides, so saying that the skill is a wanna be CD shows you're ignorant.
First, never said one was better than the other, but to assume that either is better is idiocy. Second, you'd have to be also an idiot to say IB is only needed in a few fights. Any and every fight in this game has a use for IB. IB isn't an oh shit button. It's on a GCD, making it something that should to be used on planned hits. If you're popping it just to throw it out there, then you're wasting it. For flat damage reduction which can be maintained on a boss, Storm's Path is great (10% damage reduction). And then on top of the 10% reduction in damage from Storm's Path, we also are getting 20% more HP from healing spells with Defiance. Both these aspects can be maintained through out a fight. Paladin gets 20% damage reduction, and can maintain a 5% strength reduction on the boss through the fight. So I ask, what's your point? Also, Storm's Path has a lot of strength behind it, since all the boss' damage is reduced by 10%, which includes magic damage as well, which I'd like to point out, Rage of Halone does not effect since it only lowers strength. It also means that Storm's Path reduces damage by 10% for the entire party, where Shield Oath only effects the Paladin.
Ninja brings a skill that Warrior has already, great. You obviously don't realize that Ninjas prefer it if the Warrior keeps up Storm's Eye instead, so that they can focus more on pure damage instead of having to keep up a debuff.
Also, all your quotes are snippets of what I said, leaving them lacking context. How about you actually read what I wrote instead of trying to make it seem like I am saying something that I'm not. Or maybe quote a point in its entirety instead of small bits.
