Stringing Spells Together

Hey, I was wondering if there was a way to write a macro where it would be possible to string together spells that are on the GCD, like casting Siphon Life, and then cast Corruption after the GCD, but with only 1 keyclick.

If this is against the EULA, just forget it, but if it is legal, I'd love to know.

And sorry if this is a repost, but I did use the search function as always.

It's against the EULA, because you'd need a wait function to handle the GCD, which is not allowed. So you have to press two buttons / one macrobutton twice (castsequence)

gotcha, thanks

you can string them though, with cast sequence macros, but you have to push a button for every cast.
