Hey there, I am playing a mage and I have this macro:
#showtooltip
/cast [spec:1, @mouseover, harm][spec:1, harm] Arcane Blast
/cast [spec:2, @mouseover, harm][spec2, harm] Scorch
/cast [spec:3, @mouseover, harm][spec3, harm] Frostbolt
And playing as an Arcane mage, very rarely during my rotation I cast Frostbolt instead of Arcane Blast. I know it is this macro as replacing Frostbolt with another spell casts that other spell.
This only occurs when I am playing Arcane, and there is no precise pattern I can see of when it casts Frostbolt. What I do notice though is that it happens right after a cast of Arcane blast; meaning I have not seen it occur if the previous cast was not Arcane blast.
Is this a known bug? If not is it possible to download an addon or some type of debug mode to understand why it is casting Frostbolt occasionally?
