So im trying to get this GSE working for Havoc Demon Hunter but it just wont
I have a broken hand and my friend told me about this thing
I’m not sure if its suppose to auto cast or if i just need to press the same button all the time.
Do anyone know what could cause this issue? 
You need to press the same button. GSE can’t just use spells. It needs a hardware event (a button push or a click) for each spell it tries to use. This is a Blizzard limitation that every mod or macro has to adhere to however you can do things like binding a button on your toolbar to the mouse wheel and each scroll click counts as a hardware event.
There are people who use things like Razer Synapse or Autohotkey to click a button repeatedly for them but this contains some risk.
Thank you so much. Know it all makes sense.
I will try creating a macro in my logitech g hub software, ofc there will be risk then.
As a guide the thing Blizzard are concerned about is unfair advantage. If you spam the button with a 250ms (0.25 second) pause you’re not doing anything super human and there is no advantage. Its just a case of being wise and paying attention to what you are doing
Great point, i will change it to that and see. Thanks a lot for the help!
