So with "Heal" reduced to topping off I am left with some interesting abilities. I can flame shock a bad guy and use greater healing wave or I can risk a chain heal or even healing rain followed by a unleashed weapon. These are all excellent option and with Greater Healing Wave I can crit heal 30k. However unless I flame shock a bad guy Greater Healing Wave costs a lot of mana. And the other 2 cost a lot of mana. The problem with all these especially the Shock and Greater Heal is that it takes time and thats something that healers in Heroics just do not have. Ok I know were talking about a few seconds but with the amount of damage in Heroics those few seconds can literally make or break a group.
Why bother with shocking? You have an ability called Tidal Waves. Use Riptide to set your next two G/HW's up for speed, or even CH if the bounces will hit. Healing Surge is only .2 seconds slower in this case, and thus not really worth using, unless you want the 30% crit. Sorry, but it sounds like a learn to play issue. Keep at it.
Would be worse if i used Tidal wave. Tidal wave decreases my cast time of GHW by 30% thats fine but by putting talents into Focused insight my GHW mana cost is reduced by 75% of the shock spell and its effectiveness is increased by 30%. Hence the Flame shock followed by GHW. Trust me on this I have studied the new Shammy healing a lot lately.
However even after my Op I do want you all to know that I finally downed 1 heroic boss yesterday. Sadly we could not get past the second boss and after 5 wipes decided to call it a day.
