shield of regeneration or ward against harm?

I am a protector/ward monk/ele and i couldnt decide whether to use shield of regeneration or ward against harm (both elite skills). Also, another question is since ward against harm is a water skill while all the otehr wards are earth skills, would it be wise to put points on both earth and water for all the wards, or jsut focus on one type?

Depends on what you want to do.

Wards vs. Shield huh?

In essence, Shield helps a single target on your team. Best to use on your soft targets like your casters.

Wards help your whole team, albeit containing them in one spot. If you want to protect your whole team, go ward. If you want to protect just your casters, go Shield.

The bigger question is what is the rest of you're team/guild running? You shouldn't think just in terms of you're single build but how it complements everybody else. That said, I don't think a Monk should be the person spending mana on Ward Verses Harm. It requires a decently high spec that could be better spent elsewhere. Not to mention the mana costs for keeping it up often really addup. Between those two choices I would likely take Shield of Regeneration just because it's a bit more monkish. How are the rest of your skills currently spec'd out though? Depending on what else you're running it might be better to put in Ward Verses Harm though.
