The Shadowflare slow is a 5% proc at a near 200mp cost, that's 6% of your mana pool for a 5% proc, for an AOE on a single boss fight. Plus I also said its stupid to use your Swiftcast on that spell because why blow an instant spell when you don't need too. Do you sit there on Titan or Coil casting a 3 second shadowflare on a boss fight? Do you run in to cast Miasma 2? Better yet, what do you do when you need a swiftcast to revive a pet, or raise a comrade?

You play your class however you want too, but IMHO your wasting MP on Miasma 2, and Shadowflare. You obviously must run with mage ballad all the time, but you've literally blown 1400 ish MP plus two Aetherflow moves, any chance to have blind be a useful proc (plus your tanks chance of using it) with flash...plus you run into melee range to cast a spell that will probably be sick to use in PvP...in a PvE spell. Plus you're waiting til the end of your rotation to use the longest cool down you have.
