There is nothing wrong with Berserk, with it's 50% increase in att power compared to blood for blood's 10/30% if DRG wtiha 25% dmg taken increased Berserk is still stronger.

Berserk is 50% at 20 seconds, 5 second pacification with 90 second recast
Blood for Blood 30% 20 second, for that 20 seconds you take 25% more dmg. 80 second recast

If in AOE heavy fights that's a very risky move to use for a 30% increase in dmg for DRG and a 10% for cross class.

Honestly during the pacification phase you can just use that time to spam Flash once or twice to add in bit more hate since you can't attack but you can still use magic.

--------

I think the issue is you're trying to make War(Tank) both a DD and a tank and that's just not balanced, if you did that then you would have to do the same for PLD. If PLD and WAR could pull off the same DD numbers as other DD and still tank/have a tank form there would be no need for the other battle classes.

Now rather than say that War should get new abilities, the ones you listed could be for the second job class "Berserker"

(30)Oor Dolg: The opposite of Defiance, grants the same Enrage charges and said charges are used to use other abilities.

For each charge could give a 5% increase in dmg but also 5% increase in dmg taken, so it's a give and take to either keep those charges up and risk taking more dmg or using them for abilities
Change "enmity gain" effect to "increased crit chance"
*Removes the pacification enfeeble from Berserk*

(35)Unburden:Removes the dmg taken penalty for Enrage charges for 30 seconds

(40)Rampage:5-fold attack that leaves you vulnerable, increases dmg taken by 10% for 15 seconds 5x100 potency attack

(45)War Cry (V Enrage) grants AOE dmg increase 10% and AOE weakens target's defense by 10% for 20 seconds (2 min recast)

(50)

----------

Can't think of a 5th ability but the idea is it's better to consider the second job for marauder rather than develop/alter Warrior to be a pure tank or pure DD. You can use the idea of your abilities to develop a new job that marauder can change into but trying to change the dynamics of war itself would just imbalance the class and make it to powerful.
