It happened over and over. Regrowth Glyph was too powerful, Wild Growth was too spammable, Lifebloom too strong for too little. And so we were changed, restricted, modified and retooled. We haven't turned out badly, but it does bring forth a concern about the next spell I feel is in line for reduction. Nourish.
Why Nourish? It seems like a pretty well thought out spell. It has a decent cast time, heals a mild amount of damage, and the healing power of it is increased by having your HoTs on the target (and more still with glyphs and armor bonuses). Why is it so concerning?
Well, if you look at the WWS reports of my guild's last raid (which are indicative of a trend; every raid's WWS reports have looked similar), you might notice the problem. Names blacked out for privacy's sake, first letters left because I need something to reference them by.
These are the boss healing numbers for successful boss kills of Flame Leviathan (which doesn't factor into the WWS), Razorscale, Ignis, Deconstructor, and Iron Council, with the inclusion of one wipe on Iron Council and two wipes on Kologarn. There was also a Paladin healer, but I didn't include him as it was unnecessary information.
You can see on the chart that myself and Druid T are rather close in numbers. However, there is a huge gap between myself and Druid S, a gap of roughly 1.5 million effective healing and 2% overheal (or 10% in the case of Druid T).
These are my healing spells (same fights, ignoring Potions):
Druid S used Nourish 59% of the time, had more effective healing, less overheal, and almost the same focus as Druid T. This focus was large, indicating a great amount of raid healing. With the majority of raid healing being Wild Growth, and Wild Growth being used only for 24% of the other healing, over half the time Nourish was not being used in conjunction with other HoTs. With Druid S's gear and raid buffs, there were no mana issues and no mana potions taken.
This is not an isolated incident. I have spoken with others in different raiding guilds, and their Druid healers who top the charts use Nourish just as much. This seems to be along the same lines as when Wild Growth was in its heyday. It's not mana troubling, it heals a decent amount without needing the modifiers, is quick to cast (especially with enough haste), and it makes a pretty FWOOSH sound. All indicators that Blizz devs are soon going to be looking at it and seriously considering changes, if they aren't already.
This may be paranoia on my part, but no tree who has watched the trends of change to our class and spec of late can say it doesn't bear the signs.
EDIT: Just to clarify, since one of my friends already asked me, no, I am not losing sleep over this or freaking out or anything. I'm not really worried; it's just a title.
