Ogre frontal stun immunity as a Warrior

[Healthcare]

So how critical/important/helpful is it? No doubt the raw str/sta is nice but I've never really got a melee high enough to know how high lvl mobs and the stun from them works to know if the frontal stun of ogres is extremely helpful. I'm just curious if you're basically screwed by NOT going ogre as a warrior but say troll or whatever.
