Help with Macros

[Dreadnought]

Ok so finally got my THM to 50 and decided to level a melee class.
i chose to level MRD today but i was getting extremely sick of having to press 3 buttons just to start auto attacking so i decided to try and minimize that through macros.

Currently i have to:
*Select target/draw weapon
*Draw weapon / Select target
*and hit one of my number keyed abilities in order to "confirm" thats the target i want so my character will start auto attacking.

I decided to make a macro to condense 2 of those button pushes into 1 button press which ended up being:
/battlemode
/ac "Heavy Swing" <t>

This however did do what i intended.
The "/ac "Heavy Swing" <t>" was not activating my action bar nor "confirming" my target as it does when i physically hit the number thus not activating my auto-attack. It would show up on my chat log as if the macro line was incorrect with the little sword icon above the mobs head still yellow instead of red.

Anyone know what im doing wrong?
Does anyone know of a macro to consolidate target, draw weapon, and enter into 1 button push?

In my opinion, when the mob starts attacking you, your character should automatically draw their weapon and your target indicator should automatically target and activate itself on the mob attacking you.
There should also be 1 button which targets your nearest enemy, and draws your weapon. This silly "confirm target" or "activate your action bar" nonsense needs to go.
