I use this, it's completely seperate from the action itself, so I don't need a 2nd huton button or anything. I just pop Huton then do this:

/p pull in 20 seconds <wait.10>
/p pull in 10 <wait.7>
/p in 3

It's nice and simple, tells the bard when to start song, tells other classes when to prep etc. I have it keybound to ctrl+alt+t so it's not something I accidentally hit at any other time.

And yeah, it's a macro for progression; lol @ all the posts not understanding that.
