Beloved fire mages In 7.1 Blizzard has finally added @cursor and @Player macros. To some people it is common knowledge right now, but trust me not everyone knew about it. Basically:
Code:#showtooltip Flamestrike /cast [@cursor] Flamestrike
This macro will cause your flamestrike to be instantly casted at wherever your cursor currently is. So you don't have to confirm your cast with left mouse button. No matter how good you are, you will probably be even better if you use this macro. I assume so because it most definitely smoothens GCDs rotation, at least for me and few friends out there.
Just give it a try if you wish, have fun!
