Broken macro needs repair/fixing

[Yeorgaki]

It broke when the last patch was released, its basically a macro that I use to heal my targets target if my target is hostile or my target if its friendly with alt being the modifier for self cast. The problem I am having with it is that it wont always heal my targets target for some reason, I'm no expert on macro's so I have no idea what would cause it but if anyone sees anything wrong with this macro or can re-write it in a way they think is better, I'd appreciate the help.

#showtooltip
/use [mod:alt,@player] Flash of Light
/use [help] Flash of Light
/use [help,nodead,nomod:alt,@targettarget,help,nodead] Flash of Light
/use Flash of Light
