Macros

I was wondering if it's possible to create a macro that would activate at specific moments.

Example im a destro usually around 2500 or so Hp i get to use zealot then i know that guts or frenzy is jsut around the corner.

So i know there's /delay i could use but damge input is never the same so it's hard for me to estimate the right delai.So just like the delai macro is it possible to set and HP amount.

Sumthing like:
/use zealot
/set 1990 hp( or sumthing like that)
/use guts or frenzy

If it's not possible im open to any ideas from other Destro on how they work there skill set up

nope
cant even use strings :(

well you could just make a macro that puts all those skills in one, and then keep spamming it.
like for example,

/cast zealot
/cast guts
/cast frenzy

and put it on your hotbar somewhere comfortable, like F5, and when you get low, just keep spamming it.
