Ok il explain it so you people can understand it is a thing you say, it is the EXACT same thing as making the claims ret paladin is easy mode or calling a hunter huntard.
It stems from back in the day when Arcane mage was a real 1button rotational spec it then became a 2 button spec the original place where the 2button thing comes from.
Whenever someone calls a spec a 2 button or 3 button spec it comes from the arcane and frost mage who actually at some point in wows history has been a 2 button and 3 button specs.
That is why arcane is and always will be a 1 button spec.
This is why what Thorgrath did here is so funny because he was doing the EXACT same thing without knowing he was doing it.
