So WoW goes to great lengths to limit the player's ability to macro. However, hardware solutions all seem to come bundled with the ability to macro built in. I can hit 1 button... and 3 different spells are cast.

Is this ok?
Is this a don't ask/don't tell situation?
Will Blizzard be able to detect that this is going on?

It's not like the hardware can make any kind of decision - the player chooses when to hit the macro.

Thoughts?
