Shadow wall needs an additional effect.

DRK already have -20% damage taken from Grit stance (same as PLD with Shield Oath)

WAR dont have any kind of reduced damage taken while on Defiance.

So even if Vengeance looks more powerful, in fact it's not really the case.
Different tank styles, different abilities.
Live with it.

Inner beast wants a word with you.

Besides its been mathed out that the 25% hp increase and extra healing recieved effect on defiance makes it about equivalent to shield oath.

It is fairly obvious that for spell cures the EHP is the same, 1.25 vs 1/0.8
WAR has a trivially small lower level of effective healing for magic (1 vs 1.2/1.25), which gets lost in overhealing.

Inner beast is the most powerful long term defensive cool down in the game, it puts rampart and shadowskin to shame with almost double uptime. In fact WARs low recasts give it rivalling long term physical mitigation with PLD and magical with DRK. Better in both cases if the WAR uses path.

I have Mathed this out and plan on uploading the spreadsheet after fine tuning.

T_T I'm so tired of this misconception. It's also used in the STR vs VIT debate, where people argue that since WAR have such high HP pools, they can go full Strength and still have as much HP (or more) as a full Vitality PLD/DRK when they're in Tank Stance. Completely forgetting that the larger HP pool (together with the healing boost) is our Tank Stance bonus to defence...

(Of course, the bonus to healing received doesn't work with all healing, like the re-made Lustrate or some of the new instant heals, I forget which. And there's a slightly higher degree of overhealing since we have a lot of self-heals going on. But it's still our 'tank defence'.)
