It's great that you guys want to utilize all your spells, but you're missing that honestly, the best macro is simply:


/cast Arcane Blast


That's it. Don't bother with other junk unless you have mana problems. Anything short of a raid encounter, you are making a mistake using any other spells. No you can't maintain this for extremely long (My guys can do it for about a minute, and then with a gem and convocation another minute), but it IS the best dps macro. Make it, use it, love it, forget the other stuff until you are raiding with your group.
