Thanks for the helpful reply! I actually have a Logitec mouse that has a bunch of buttons on it so I'll look into macroing them when I get off work. Also, I actually did find a way to do what I was talking about in the original post...

/macroicon "Dreadwyrm Trance"
/action "Dreadwyrm Trance"
/hotbar copy current 1 current 4

This switches me to a new hotbar upon casting Dreadwyrm Trance and then to go back to original hotbars...

/macroicon "Deathflare"
/action "deathflare"
/hotbar copy current 1 current 5

This switches me back to my normal rotation bar. Saves me 2 buttons to press. But it sounds like macroing to my mouse wil be even more helpful
