In regards to macros, they don't hurt other players...
But Blizzard did draw the line at the removal of the fall-through and the removal of the ,,,,'s for timing.
And has clearly stated, they want players to make the decisions, not an addon or macro... and further, has been consistent in breaking addons/macros that allow the mindless play...
Our whole 'mindlessly spam the button' is gaming the system by removing the decision making from the player.

So, if the line on respecting Blizzard is when it impacts other players.
But it's okay to bypass restrictions Blizzard explicitly put in the game to prevent 'mindless' spamming... because it doesn't impact other players...

Basically just want to know where the admins consider the line to be.
I can remove, or at least edit out, the whole priority system section on my Pally/DK guide... and refrain from offering support in that direction.
