I used the predetermined x,y cordinates mouseclicks in hotkeynet for a while (against the author's advice), it worked great. But I felt it looked REALLY suspicious so I stopped using it, and switched to the normal keybinding mouse clicks. Using the predetermined X,Y system, It puts down the AOE in the EXACT same pattern every time, and I was worried that it be a red flag to see every AOE I casted was clicked in exactly screen position 600x600. I honestly don't know if this is a big enough deal to warrant any blizzard attention though. I think it'll come down to a very specific blue post, or someone getting banned before we know if it's acceptable.
