stressful pvp-situations: heal und dps at the same time

In pvp i often spam lightning bolt liky crazy, if i get damage i must use my special keys for dps and Heal:
Key1(heal toon1 and dps target): toon1 and toon2 heals toon1 and all other dps the target
Key2(heal toon2 and dps target): toon2 and toon3 heals toon2 and all other dps the target
... and so on

Would it be possible to make a script for my normal lightningbolt-key like:

Toon1-makro for Lightningbolt:


If UnitHealth("player") < 70%
{
cast [Target=Toon1] lesser healing wave
}
else
{
cast lightning bolt
}

no since 2.0 conditionals are a big nono

Can't have the macro do the thinking for you, however you can use alt/shift/ctrl to do it.

/cast [mod:shift, target=party1] Lesser healing wave; Lightning Bolt

Hold shift and press the macro to heal party1 (or whoever) or just press it to cast lightning bolt on your target.

*Untested, but I believe the syntax is correct.
