I changed my mind..

Regarding the FL BoP 365 Healing/caster trinket Moonwell Chalice..
Swapping out Core of Ripeness..
Keeping Fall of mortality
As I have 2p-set 359 and 2p-set 378, my spirit is 2738 unbuffed, and more mana regen should not be needed atm.

The mastery here will be great for Beth, Domo and in particular Raggy as raid healer.

Resto shaman Mastery:
Deep Healing
"Increases the potency of your healing spells by up to 0%, based on the current health level of your target (lower health targets are healed for more). Each point of Mastery increases healing by up to an additional 3.0%."

I had a short discussion in Gchat with other healers on this trinket. Anyone has thoughts on this?

If it's anything like the tanking trinket from the same vendor then you'll have to stay in the moonwell to keep the buff.
On most tank fights where I need it I'm normally static, whereas healers I think need to be quite mobile. That makes it more situational yes?

As a drood its said 2500 regen is enough for firelands ... last week i was on 3000 ish....  did a jiggle and reforged all i could to haste and mastery. Im now sitting at 2450 regen and not feeling any mana problems. So the question is if its just for regen and you are finishing the fight with spare mana it may be possible to loose some of that spirit for bigger healz. To put it into usefull numbers ... My big heal was 60k....last night after the reforge i keep seeing 75k pop up. I use the moonwell, you get a beam (link) to it and you cant get out of range.

When you hit reveared with the firelands npc you will get at least 1 new trink and possibly also like the look of the dps caster one too

As you have the T12 2 set with the riptide regen then losing the Core of Ripeness is no loss and the FL trink will provide a much needed boost on demand - seems a no brainer to me.

Ill keep it i need the regen even though my spirit isnt much lower then yours but its much needed
