Macro help

[Stargolem]

Hey Guys,

i have 2 marcos:

1) bind on "1" - normal cast Immolate, with "alt" cast Curse

/cast [mod:alt] Curse of the Elements; Immolate

1)Harm macro

/cast [harm][target=targettarget,harm] Immolate

Its possibble make 1 macro ... when i have in target enemy, use immo or curse, and when i have friendly tar, then cast on her enemy with mod alt??

/cast [mod,harm][mod,@targettarget,harm] Curse of the Elements; [harm][@targettarget,harm] Immolate

Like this? Casts on harmful target else harmful target of target; mod for Curse else Immolate.
