Black Widow on the fly recordings and WoW ULA

Hi, I have a Razer Naga Trinity, a Razer Tartarus and Black Widow(recent purchase) I have used the Tartarus and Trinity for years in Wow without issue and use them to keybind only. I want to use on the fly Macros with the Black widow. However it seems this may not be allowed in WoW and could get me banned before I do that does anyone actually know the answer? Blizz response was if you have to ask don't do it basically!!
