Legendary Healer Item?

[MongoJerry]

I have not crunched numbers to see what is best, to spam flash heal or go for my greater heal though, perhaps the difference for my character is currently smaller.

Consider also using low rank versions of Greater Heal, especially as you gather more and more +healing gear. In my epic'd out state, I can cast rank 1 Heal (not Greater Heal) for 850ish healing for 131 mana. Basically, I can cast this heal indefinitely, which makes it fantastic for long fights. Next to that, I have Rank 1 Greater Heal that heals for about 1600ish healing (and now another 1000 healing hot, since I just completed my Transcendence set. Woot!) for about 300ish mana. Rank 3 Greater heal heals for about 2500 health, so I use it when I need a little more firepower. And then, I use Rank 5 Greater Heal when I don't care about mana (e.g. I'm using Inner Focus or a fight is going to be over quickly).

Since you obviously don't have the +healing gear I have, you probably can't drop down to as low of ranks as I can, but experiment around with using various ranks of heals to see what works for your equipment setup. Generally, the lower the rank the heal, the better your mana efficiency, especially the more +healing gear you use.

Make sure you're using Renew as much as possible. Also, Flash Heal is still very good, even if it doesn't have the same mana efficiency as Greater Heal. Basically, I use a 2.5 second heal if the tank is at or near full life. But if he or she isn't, I throw up a Flash Heal.
