So what exactly IS the issue with Warrior?

[Giantbane]

Its a 33% damage loss for using defiance.
Its 25% for a Paladin.

33% for using defiance? 25% for Paladin?

How do you figure?

33% for using defiance? 25% for Paladin?

How do you figure?

Look up the abilities and read the tooltips:

Defiance: Increases maximum HP by 25% and increases enmity, while lowering damage dealt by 30%.
Shield Oath: Reduces damage received by 20% and increases enmity, while lowering damage dealt by 20%.

So for a class that should be self-healing through damage, it takes a bigger hit through it's def stance, plus

The 10% crit +maim+SE just barely overcome the debuff.
Barely.
its a very small amount.

Personally, I find it awkward that WAR's second cross-class is MNK, I never really see anybody talking about using it's abilities. I thought LNC (Keen Flurry, Life Surge, Invigorate, Blood4Blood) would be more appropriate (and for a while I thought this was its cross-class- seemed logical).

Probably saving LNC X-Class for Dark Knight. Makes sense.

33% for using defiance? 25% for Paladin?

How do you figure?

Because increasing your damage by 25% =/= lowering your damage by 25%.

If they were the same, increasing your damage by 25% would nullify it, that is not the case.
To nullify it, you need 33% more damage.

Its the same reason why Shield Oath gives equivalent eHP to Defiance.

20% less damage taken = increasing your hp by 25%

Edit: Babylyn: Its a 25% damage debuff.

For a Paladin, they suffer an overall damage loss of 25% because its 20%damage debuff.

Do the math.
Lowering your damage by 25% means your damage is down by a 1/3rd of its original value.
