pitty you should rearrange your macros to fit your order
Dunno how yalls MT's pull, but I'll usually run out with the tank and get off Despoil, Siphon STR on the inc so I dont bother with those casting times during combat. When you are talking over 8k dps, squeezing anything prior to engagement will give you a considerable bonus. Then I jump on the mob like its a free hooker.
...follow up with the haste atk, which starts my autoatk, then agony and sac... By that time dispatch has landed, then DM followed up by all my spells in between autoatks. Don't really have an order... just go by feel.
The timing of POTM and Chime can also twist my stuff around... I usually have a good feeling when they are coming up so I know if I need to reserve different stuffs or not.
Having ACT and a G15 helps too!
