Shadow wall needs an additional effect.

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.
