How noticable is the Ogre stun resist?

[Grakken]

Really depends on your playstyle. If you're always playing in a group no. Iksar/troll regen is very noticeable.

I've always had FSI envy. Playing shaman many times. Went ogre FSI this round and I've had countless times I was so glad I had FSI. From, putting your butt in a corner and channeling Gate with 8 mobs beating on you and get away, to breaking a tough camp and needing your root to not be interrupted.

I wouldn't trade FSI for anything. Breaking a camp is so much easier on an ogre I think. Troll is definitely a better pick for a group comp. But, most people are afk half the time in groups anyway and a 5% efficiency improvement Troll get just goes unnoticed.
