Attack targets target

It is possible in wow to assign to attack targets target.Like u have a tank in grp and u are ranged dps,u have tank targeted all the time and u attack what he attack.
Is it possible to do so with multyboxing?Like my other characters target my main screen character and just attack when he attack,whatever he attacks without spamming assist me shortkey all the time i switch my target?

Sorry 4 spamming forum these days wow is a bit complicated than d3

That's not really how we do it in World of Warcraft and other MMORPGs. (Except for Lord of the Rings Online, which it is typical to use the game's "Skill Target Forwarding" feature and keep your tank or whoever targeted.)

By default, when you press 1 through =, these keys auto-assist and then broadcast the same key. So you press 1 or 2 or 3, and you have abilities on those buttons in the game, and your guys will take the same target from the guy you're playing, and attack it with that ability.

Are you using keys other than 1 through =? You may just need to add the same assist and broadcast capability to your additional buttons -- WoW Quick Start Guide: Quickly add many hotkeys, optionally with auto-assist

Ok lets say i engage mobs with my fireball that is on Straight Key Broadcast key E can i bind ASSIST ME in isboxer on E also.So basically when i engage on my main with E (fire ball) i also use ASSIST ME and rest of my characters attack the target ?

No, instead of using "Straight Key Broadcast", you are wanting "Assist and Broadcast"

So if i bind all my damage spells keys on "Assist and Broadcast" i don't really need to use ASSIST ME key for my other characters to engage mob that i am attacking with main?

Yes, that is exactly the purpose of "Assist and Broadcast", so that when you use these particular keys, your guys automatically assist and you do not need to manually make them assist.

Thanks 4 the help
