Is macros cheating?

I'm a huge fan of macros. The way you can make more actions with a simple click. Some classes are more macro "demanding" than others but all in all a macro can enhance your gaming.
One of the more used macros is a "when shit hits the fan" macro - a macro that pops all defensive CD's and buys you that extra few seconds of life to change the situation.

The fact that macros is a built-in feature makes it a legal way of making automation and/or make more functions on the same button - like changing stance or maybe even outfit from PvP to PVE.

One thing that puzzles me though is how far you can go before other players see it as cheating.
If you have a macro for the opening spells that you use on every encounter then it's seen as ok by most players. However if you have been a little too clever and created a full rotation macro (one key macro) then people tend to call it cheating.

For one I'm all for macros in every aspect. If a person is smart enough to create a valid rotation in a macro I think that's great. Some players even need macros like this as they might have hard time with muscle memory, damaged nerves or even miss fingers. So in no way do I see it as cheating. Hell, I use one button macros myself - mainly for LFR or when farming old content - and I love it.
Rotation macro on mouse wheel and spin the crap out of the mobs.

In LFR and dungeons these macros have made me top the meters with both my Death Knight, Druid, Priest, Mage and now Hunter. I don't use them constantly but if the group is working well then I start spinning the wheel. As for right now while gearing my Hunter I can be top 5 in LFR even with weaker gear than some of the other players.

The key to a good macro is knowing your latency as it can greatly influence your macro with some classes.

I do know that if you raid on a more serious level then rotation macros are not the best way to go as they take some control away from the player. But calling it cheating is not fair I believe.
But try it out and do like me - spin that wheel of fortune.
