Sadly sayiing goodbye to SCH

Ideally, if you can stand still for the entire fight, say on a practice dummy, you will never want to weave in Miasma II on a single target.

Broil II > Miasma II

However, because most fights force you to move at some point, being able to get on a 3rd set of dots to tick while you run away spamming Ruin II during movement phases will help maximize your DPS. Basically, lower DPS is better than no DPS during mechanic phases where you can't stay still to cast Broil II.

Edit: Using auto attacks, won't make up the difference.

Miasma II + Energy Drain (plus letting the M2 DoT run it's duration) is more DPS than clipping the GCD with Broil II + Energy Drain. Really, if you can spare the time for Miasma II's animation, you're better off using it for just about every oGCD that you don't have Bio II for, rather than clipping.
