few things to add:
1) focus target Twinny and have a virus macro: /ac "Virus" <f> for pre Aetherial profusion
--you're already going to be pressed for time getting tank topped off and putting aldo up, so a virus macro at the least should at least save some targeting time

2) some people place fairies, others don't, but for divebomb phase, you really need to be doing it. place fairy next to and to the side of crevice area.
