1) You would have to create two macros, one used to turn the song on, and one to turn it off.
/ac "Mage's Ballad" <me>
/wait 3
/p <se.3> --- Ballad ON

/ac "Mage's Ballad" <me>
/wait 1
/p <se.3> --- Ballad OFF

However, if you hit the wrong one, it would still toggle the song and display the wrong text.


2) Yes, macroing text disables the command queue. Even if you made a macro that only used 1 skill and did nothing else, it still disables the command queue because it is a macro.


3) Realistically, there are very few situations in which you will want to sing Paeon. Since you can't see party member's TP, it's up to them to tell you when they need it. Really the only situations you should be using it are: a) if a tank runs out of TP and is about to lose aggro b) if you have several melee in the group and they have to spam AoE such as in Turn4.


4) Well you don't want to spend TOO much time singing/canceling/singing/canceling because every time you have to put it up and take it down you lose about 4 seconds of your own DPS. So I guess it just depends on how well you know your healers. If you can be relatively certain they won't need Ballad, I would run Foe until I was completely out of mana so that I spent less time casting/canceling songs. Of course the half/half method is safer since you would always be able to ballad if things went sideways.
