Healing as a Pally

Ok, I am going to start down a road of advice for general raid tips for healing as a pally. I am going to start in ICC normal and pretty much jot down everything I find useful in every strategy I do.  I think wing by wing might be the go to start off with, might even critique all the Phat Lewtz if they bear a comment (not everything always does - a lot of pally gear is a no brainer).  I will try and comment on when all our pally tricks are useful above and beyond the usual "OH CRAP A WIPE Ummmm I will DI THE TANK!"
