Well, assuming that we're not ALL draenei... if you only need 2% (or 1% for draenei) +hit from gear, you can use your other sockets for....?

Though, I do admit, alot of ele gear is littered with hit -- in which you'd probably want to rearrange your points once you reach that.

Nature's Guidance would be the weakest stat for elementals, who rarely if ever melee. I'd go Ancestral Healing for those clutch Hydross nature form moments when you find yourself spamming rank 1 healing wave on the tank in the hopes that it procs the armor buff so you're not TOTALLY useless.
