Prat, and it's Delay macro command

I agree, It can't be used to do anything important, but I can't argue with the fact that the GM said it would be a bad idea to use it, lol.

Actually he meant that using a G15 or some other external system to general a delay was bad, but a delay generated using the in-game systems was fine. Scroll down to the end of the thread -- he clarifies.

Guys this is the quote from the blue response (emphasis is mine)

No, time delays inserted into a Macro are almost always not okay - this is largely part of the reason why certain macro functions of the G15 can cause account actions, as well as the macro functions attached to some of the newer gaming mice.

That said, our base macro 'language' does not allow for delays on 'hardware' events. Communication based delays specifically shouldn't be an issue .

the last paragraph is the key point here, reading between the lines, he is saying that the built0in scripting engine can't be used for delays and hardware events and therefore is safe to use. If they don't want this functionality they will change the engine, much the same way they removed minimap ping :( will just re-iterate this Communication based delays specifically shouldn't be an issue

As it uses The built-in macro language you are safe... if Blizzard decide they don't like it they will issue a warning, it is very unlikely there will bans on something that is epidemic in wow community
