Wildfire Riders

Unless Aura A and Aura B are both stances, you'll probably need to use script for such a macro, which means I can't really help you. However, for basic macros, you can always check Cogwheel's Complete Macro Guide and various other good macro-writing resources stickied on the official UI & Macros Forum.

Yeah, I think back in the day they disabled all abilities to have macros "make decisions" for players on that patch that broke every single mod known to man. I remember it as the one where Decursive hit the dust. Was it 2.0?

Just out of curiosity, what exactly did you want to macro? You may not be able to make a smart macro to do what you want, but you could potentially create a dumb one with pseudo-similar effects.

Looks like he wanted a macro to use slam if Bloodsurge procced.

All I can really say is lrn2procwatch >.> <.<

Edit: Also, scrolling combat text lists it as !Slam! or something to help. Though I can't always fit it in, especially with tons of AoE going around and things dying all at once.
