So I always start the fight off doing ABx3, PoM AB, pop trinket, IV, AP, Mirror Image and then Missile Barrage, continue with my rotation. This assumes I know when Heroism is coming and I can do this safely and have them all off CD when we pop it.
My problem is I have no idea what to do with them after the first cast. Trinket is 2 min, AP is 1.4 min, IV is 2.4 min, and Images are some other not nice number.
Do I pop them as soon as they come off CD (assuming Patchwerk-like fight) and whatever is up for Heroism is just dandy? Or do I wait to pop them all together again, or stagger certain ones, etc?
I do make sure not to pop IV at the same time as Hero since I cap, so that's always used right after hero ends.
