On the healing forums, in the first GC post we’ve had there in a while, GC confirms that the reduction in duration for rejuvenation in 3.3 is intentional.
We don’t want rank 15 to have that extra tick. It is technically a bug in that we didn’t intend for it to have that behavior, but obviously we sat on the change for awhile. However since the popular Resto style has now become Rejuv on as many people as possible, we thought the extra tick had become problematic. Frankly we think druids can absorb the small nerf without hurting their overall healing much.
We’re not trying to hide a nerf, and we can certainly change the patch note to not say bug fix if that makes it go down any easier. We’ll look into any discrepancy in numbers between rank 14 and 15 and make sure things are working as intended.
I also wanted to point out that this “change” isn’t effecting the amount healed by swiftmend, because swiftmend was always based off of the original 12-second rejuv, and swiftmend was never changed to take into account extra tick(s).
You also still get a 3 second duration increase from Nature’s Splendor. So,the final total is 15 seconds with talents (down from 18). I’m betting that the last tick was likely overheal a lot of the time in the majority of fights, given that my overhealing from HOTs is usually near 70%. The real bummer is having to lose global cooldowns reapplying rejuvenation on people like tanks that you need to be able to easily swiftmend. Or, for having fewer rejuvs already on raid members to be able to benefit from having it up to buff nourishes or allow swiftmending of your raid members.
This also further discourages the “blanket your raid with rejuvs” behavior that some druids have still been doing, as it allows for basically 2 or 3 less rejuvs (depending on how fast you got them up). You should have known better, anyway, since Blizzard has established a history of nerfing any druid spell that takes up more than 40% of our total healing done. Even just the T8 set bonus change, and the increase in burst damage in ToC 10-man was enough to get my rejuvenation % healing done to drop from about 60% in 3.2 Ulduar raids to about 30% in 3.2.2 ToC raids. Nourish, instead, is climbing up on doing a sizable portion of my healing done (though still below rejuv & wild growth) – even before the rejuvenation duration nerf. People should be moving away from the “keep rejuv on as many people as possible in a 25-man raid” style of healing in 3.3, if you aren’t adjusting your healing style in small ways already.
As for what the new rank 15 rejuv looks like: “Now heals the target for 1352 over 12 seconds”, is down from the 1690 from the original tooltip currently on live. The rank 14 tooltip is: 1192 over 12 seconds, so it’s still theoretically a 160 healing increase from rank 14.
The healing upgrade from rank 14 to 15 rejuvenation is in line with the change from rank 13 to rank 14 renew, which is 165. So, it is unlikely that rank 15 rejuv will have it’s amount healed buffed in any way.
It’s not really a bug fix, it’s a nerf to the amount healed from rejuvenation. Part of the reason it’s likely being done now is to make it consistent with previous ranks, but the timing of it isn’t just in preparation for removing lower ranks of all the spells in Cataclysm – it’s because they thought we could absorb the nerf now.
