Well warrior have it both tough and easy.

Easy because if you are full on vit, you will have so much HP you will not get one shotted like a pld caught off guard. So face tanking is a lot more forgiving.

Tough, because warriors suck at damage mitigation. IB is not an Off-CD skill making that 6 seconds even worse (It's coming...omg CD!).

Vengenace is too long a CD to rely on more then once, and foresight is crap due to only being physical. Conv is limited since you already have massive healing surplus, and blood bath won't really do that much nor 2nd wind (and it's 700hp heals is it even worth a slot?).

Thrill is probably useful but limited, and realistically a war shouldn't be one shotted even unprotected.

So really, It's Inner beast/Vengeance or nothing. Foresight maybe if it happens to be physical, but everything else you might as well be used on CD, as the impact the fight very minor comparatively (though obviously some phases are more intense then others).

There isn't as many tricks as pld, for a war. Just gotta live on being good for IB when crap is coming.
