I use Key-clone and i have binded to switch between my 3 characters to F9-F10-F11 and it works fine most of the time.

But when i switch the 2 other slaves they dont assist me, because my macros are based to the Main char. I have seen videos like IS-boxer and stuff like that. when they can switch fast and the slaves keep assist and cast with one he switched to.
Can someone please tell me how to do that.

Can someone please help me? Shud i start with IS-boxer insted if that is required?
