Are there any combat macro's that actually work?

The only one that kind word are the hotbar switching, and people mainly use it to switch between AOE and single, so they don't have to bind them to different key. So for example your single combo is bounded to 1-6 on Hotbar 1, you put your AOE combo on 1-6 on hotbar 7, then have a macro to swap the 2 hotbar as needed.

But macro don't really work if you want to chain combo itself.

That's wild people do that, because there's an ingame function for this already that doesn't use the macro system.
