Ruin 2 is truly the biggest waste of MP to use while you're not on the go. I understand that this advice may have been given in hopes of assisting the OP with T7 kiting, but the kiter is not always kiting. Ruin 2 should be used impromptu of the caster-- meaning you need to make a proper judgment call on using it, since it does cost 80% more MP to cast it than simply casting Ruin 1. I should also note that they do the same exact damage, since the potency of the two abilities are identical. You should also note that the amount of DPS gain from casting Ruin 2 over Ruin 1 is completely marginal (roughly 1-2% more dps across a long fight). IF you are receiving Mage's Ballad often enough, then casting Ruin 2 in your main rotation can be okay, but if your Bard dies at all, then that too will be subject to change, since the Bard will no longer have the necessary MP to cast the ability... Overall, good advice though.
