I always use trick attack at around the first 15 - 25 seconds in a boss fight. That's when the BLMs are starting to use fire IV, the MNKs have build up the grease lightning III, the SMNs are ready to cast tri disaster with raging strike and deathflare, etc.

I use DWD when all the debuffs are up or also the need of burst to kill adds. Duality is best used with Aeolian Edge while all the debuffs are up too.

Because they give better damage with the debuffs up, I haven't tested it yet, though.
