Wars don't need more damage, the other tanks need their damage increased to be on par with the crit damage the War can put out. My PLD is only 3ilvls higher than my War only because the War has Al-M weapon and PLD has plain Lost Al sword-shield. On a 69-70 mob with the slashing debuff berserk and stormseye up and doing a fel cleave it can reach 14k-18k per use. Now that being said I can barely reach 7k-10k with fight or flight+Royal Authority. Now to me if Spirits Within is "suppose" to be based on actual maximum HP instead of just a potency rating with 55k HP it should be critting well over 20k.
