Ok so I started off by just have a cast sequence mixed into my DPS mash button. Its pretty much is just Riptide. Lesser Healing Wave spam....

It works good but pretty much after every fight my Resto Shammy is out of mana. I don't die now but is there a better way to handle this? I'd rather not have it on a third button I need to spam but I guess I could if I really need to.

Thoughts/comments?

Edit: Needless to say I got my first Heroic Boss down BARELY, but I did in Utgarde Keep I got the 1st guy down after a few wipes.
