Ogre Shaman Creation Question

[Mayhem2]

For those of you that have created an Ogre Shaman.

Did you place +5 into AGI to bring it up to 75 in order to avoid the mitigation penalty?

Or do you just rely on your AGI buff to get the job done?

At the moment I'm thinking 25 WIS, 5 STA.

I know a few people has suggested to put all points possible into STA.
Since shaman only get 2.5 hp per point of STA, it seems like a waste to dump 25 points into STA for a measly return of 63 hp's.
