Pretty much, you can command your toons to follow the current Jamba leader, via a macro.
Or you can have the addon... strobe the auto follow command every second, and to reinitiate it immediately following combat.

I prefer the manual macro for follow, so I can position toons to avoid AoE or whatever.
In that case, you make it a habit to click the auto follow macro before you move.

You still need to click your attack macro's.
Most of us have either a Big Button, or 2 to 3 combat buttons.
On the main, it might be Fireball spam.
On the alt, assist the main and spam Shadowbolt.
But you still need to press the macro keys.
You get the idea.
