I use both arcane power and mana gem (and other cooldowns I have) to start the burn phase. Is this what you mean?
Also, where does POM come in the cycle? I usually use it during burn phases but also to conjure mana gems when I use up all my 3 gems. Do you tend to need more than 3 gems per heroic fight? Or am I doing it wrong?
