Air of Enchantment-Only for smiting?

I played around with a build today using air of enchant with a prot monk and 16 divine favor, I liked the heals and protection it allowed, self protection is an issue, but its not much of a problem.

So, is the recharge far too long to be used in practical monking or am I missing something?

Our GvG is experimenting with AoE as a prot skill rather than a smiting skill. It's worked okay so far, but yes, you have to rely on the other Monk more than usual because AoE doesn't work on yourself.
