Partly I think it’s not working as I expect it to, partly when it does work, it stops working.
No macros, no addons, no fancy computer software mimicking macros or anything like that, just a spell from my spell book placed onto my default UI action bar and that’s it. I press the button, sometimes it casts once and stops, sometimes it casts multiple times and keeps casting.
Sometimes I am doing my rotation, hold down a button, press and hold my next spell and sometimes it casts once and stops, sometimes it doesn’t even cast at all.
How I think it should work, effectively is to just mimick me spamming my buttons down. Or at least fix it so it works everytime when I am swapping buttons and using other spells, because right now you need to basically spam your second spell and then when it starts casting to hold it down, which is a little silly for some classes where you may only have 2 charges of something, may as well just spam the buttons myself.
