Enchanting on all characters is nice if you plan on demolishing LFR each week on 5 characters, otherwise just do what has been suggested -- slap it on a healer or someone, I don't find the ring enchants THAT useful (I've not really done any other professions lol, enchanting made me too much gold).

As mentioned before, definitely aim for MoP LFR content at minumum, it's enjoyable.
