Question about advanced Macros

[Aikarion-emerald-dream]

I would like to know if it is possible to create the following Macro:

I want to cast Scorch until Hotstreak (2 crits = free instant pyroblast) activates, once activated, The Scorch button becomes Pyroblast. Once the Pyroblast is launched, it reverts back to Scorch.

Is it possible to make a macro that changes one ability is used based on certain conditions being met like this?

I don’t think you can macro this. You might be able to find an addon, but it seems like something Blizzard wants to discourage, so maybe not.

3. Macros - What can they not do?

Macros cannot make smart decisions for you. They can’t cast spells based on cooldown, or check if a buff is active, or magically fit all your abilities onto one button.

Sure isn’t. Your best option is to use modifiers.
