Well I guess I worded it wrong. I didn't really mean attack for me. I have macroed to most of my attacks like heavy shot, straight shot, etc. to see if bloodletter or misery's end are available, and it will trigger that attack before continuing with the main attack.

So If I was heavy shotting way, and my dots fall off, is there a macro that will trigger windbite when i do my next heavy shot? Same for venomousbite and also a straightshot when procd.

Edit: Okay. I get what you are saying. Thanks for the info.
