Shaman Race?

[Hibren]

So as far as min Maxing goes, Troll/Iksar vs Ogre -

Does being unstunable outweigh the regen at higher levels, regen seems really lackluster on a class that can heal itself? The tiny AC boost from Iksar seems okay but the giant sta and therefore hp pool for ogre seems like its best for min max? I know wis hardly matters since 200 wis is easily broken with some decent gear.

Thoughts? I already have an Iksar shaman but hes only lvl 12 and im considering going over to Ogre? possibly Troll.
