Are there any drawbacks to action definitions?

Coming from Warcraft 3's editor, I'm pretty suspicious of anything that makes triggering this easy. Is there a drawback to using these action threads? I'm making huge huge progress with my baneling bowling map just by stringing together action definitions, and I don't want it screw me over in the end like in War3 when you first realize you cant make spells MUI with global variables

Nope. They are actual functions in Galaxy, so there won't be any problem with it.

And yeah, they are incredibly useful. Another thing Blizzard managed to do right about GUI this time around.
