I only use 2 macros currently, though I'm thinking about trying that fire/bliz one with the mouseovers posted on the previous page, looks promising.

/macroicon "Thunder II"
/ac "Thunder II"
/ac "Thunder"

That one will cast thunder 1 if you don't have enough mana for thunder 2. Very useful as the dots tick the same (and yes thundercloud procs from thunder 1 ticks). I don't see the need for thunder 3 because of it's extremely long cast time.

For AM I use this

/macroicon "Aetherial Manipulation"
/ac "Aetherial Manipulation" <2>

That way I always put my white mage, who I trust completely, to be my target. The mouseover one works very good as well, but I find just smacking that gets me out of where I don't want to be faster. If I Don't have that whm to play with then I would use the mouseover one. Don't put manaward and manawall in the same ones, different types of damage and you could very easily need them at different times. Say you want to give healers a break for conflags in t5 then get a few extra casts in during dive bombs, you'd need the separately. Though the one with both in with a limit break does sound nice, I'm gonna try that later.
