Speaking as a Blizzard programmer, I can tell you there is no basis to that rumor. Edit: just to be clear, I'm not discounting the rest of your points. It is indeed possible to do very sophisticated things with triggers, rules, or what have you, you just tend, in my experience, to wind up with something significantly harder to read and maintain than something written more traditionally. Which is probably why Blizzard's RTS's include actual scripting languages as well. "Probably" as in I am a Blizzard programmer, but I'm not on the RTS team and haven't worked on any of those games directly other than a tiny bit of Battle.net code for SC2. It's possible, even likely, you know more about SC2/WC3 modding than I do :)
