Honest question.

Has anyone done parsing to find if there is any relevant difference between using Ruin2 over Ruin1 to fit in a single off the gcd ability at no time loss? As is, unless I want to fit 2 or more off gcd abilities together I just use Ruin1. ie RS > Bio 2 > Miasma > Bio (fester) > Shadowflare > Miasma 2 (contagion) > Ruin > Ruin > Fester > Ruin instead of using RS > Bio 2 > Miasma > Bio (fester) > Shadowflare > Miasma 2 (contagion) > Ruin > Ruin2 > Fester > Ruin -- I don't feel like the DPS difference is significant enough to warrant the extra mana spent (obviously this isn't an issue in short fights, but in longer fights where i spend more mana on dots or need to rez it can become an issue)
