Macros are they needed?

I would use these if casting out of turn wasn't an issue:

/ac "True Strike"
/ac "Demolish"
/ac "Bootshine"

/ac "Snap Punch"
/ac "Twin Snakes"
/ac "Dragon Kick"

/ac "Rock Breaker"
/ac "Arm of the Destroyer"

[...'

/wait

let's say the GCD is 2.5 for all these abilities, your macro spam/rotation would be something like this:

/ac "True Strike"
/wait 2.5
/ac "Demolish"
/wait 2.5
/ac "Bootshine"
edit: and you click the macro once until the whole serie of abilities activated to avoid the problem you mentioned.
