Okay so I've been playing around with it and I've come to the conclusion that it's the use of both Thunder and Shadowflare. Both are too mana intensive when used together however I did find that if you use one or the other, the mana is manageable. Shadowflare should be used in AOE situations obviously and Thunder for single target.

Another thing is that you don't use Energy Drain. Energy Drain is 150 potency, instant, and returns 50% of damage dealt as MP. This is an especially great spell for mana sustain because it scales with gear. The better your gear, the higher damage you do and thus, higher MP returned. You should be weaving Energy Drain alongside your Ruin II's after a full set of Fester (one stack goes to Fester, another stack goes to ED)
