It appears to have been hotfixed. I tested in dalaran pre-raid tonight and it was not working on instant spells. About 45minutes later I said something to another druid in our raid and he reported that his was working fine. I put mine on and all was well.

Cat version of swipe radically changed my attitude towards trash pulls in Naxx. I was afraid that with such huge energy cost, it won't cut it, but seems that it works pretty nice, especially if preceeded with single point SR (that could be tricky sometimes, since after two GCD needed to get SR running, trash is half dead usually... still, it seems to be worth it, at least with those spider packs). Positioning also seems to be a little trickier than in case of bear swipe, but nevertheless, it turned out to be better than I expected.

I got a strange feeling that my single target DPS... decreased a little bit (I rather expected that it will increase a little bit, considering Rake fix; even despite I can't use the weighstone anymore). Of course, one evening of laidback Naxx raid isn't anything that I should base my conclusions on. It's just a feeling that I will try to check more thoroughly on the dummy tonight.

I noticed some misses after the patch while being hit-capped. I went to target dummy and found out that Infected Wounds miss occasionaly. I guess it uses spell hit formula, but i never noticed it before patch. Was it like this all the time or did it change with 3.0.8?

Infected wounds, Feral Faire Fire, Growl, etc.. always used spell hit formula.

The talent Savage Fury got "fixed" (was counting twice for mangle and not for rake), resulting in somewhat lower mangle damage. That may be at least part of the loss.

It looks like moonfire's animation was changed by the patch

I definitely noticed a difference. I really wish I could put numbers on it but I'm unable to.

The first run we had post patch my dpsers immediately noticed that my threat was lower than usual and I agreed. AoE threat as well as single target threat. My dps hasn't even really gone down, just my threat so I don't expect that it's coming from the Mangle fix at all. I think they changed how much threat our spells generate but like I said, I don't have numbers to back it.

I warn that this is personal speculation, but if true would definitely be important to know... I believe Protector of the Pack may be bugged.

Saturday night, we did some 10-man 3 drake attempts, and got quite well acquainted with the damage range of his breaths during the dangerous phase, as it was more than my HP (I use a very HP-heavy set).

Sunday night, we go back in with the same comp, and the breaths are hitting about 4k less. I'm not talking resists - I mean the total damage (landed+resist, no absorb). These numbers are from over the course of a few hours both nights, so while I regret not having any WWS proof to "confirm" this for anyone, I am least personally quite confident that something was causing a significant decrease in breath damage.

There was no downtime between Saturday and Sunday night, I had the same gear, group buffs. The only difference was Sunday afternoon, I respecced for PvP for the first time since the patch, then specced back to my tank spec for Sunday night's attempts. And suddenly was taking about 12% less damage from flame breath.

I'm concerned that with the change to Protector of the Pack's mechanics (no Guardian buff now), it may be bugged and not active until you unspec and respec it. I certainly would hate for this to be incorrect and scare anyone into wasting 50 gold, but if anyone has not respecced since the patch it may be informative to put on 0 resil and have someone DOT both them, and something with no spell damage reduction, to compare.

I confirmed last night that (at least against a warlock's Corruption DoT) my Protector of the Pack was functioning properly - I took 12% less damage from the ticks when I shifted into bear form. I haven't respecced since the patch. So, it was at least not bugged for me. I'd like to see a few more people confirm or deny though, since 12% mitigation is a pretty big concern, and there could be other factors than respeccing that cause it to only happen to certain people.

I was working on OS10 last night and I didn't notice any reduction in damage at all. As of 3.0.8, we were experienceing a lot more MT deaths to 1 shot since you can longer twilight dance. I really wish they did increase our damage reduction because it sucks to have a great attemt end due to a 50k breath.

It's not nearly as significant for druids as it was for priests because WG is a HoT while CoH was instant so for instance on Loatheb, you could precast WG 4 seconds before the aura wears off on one group of people, Nourish someone, and then WG a different group. I'm fairly certain (correct me if I'm wrong) that WG has a higher healing value than CoH, so on Sapphiron and Malygos Tornado, it's going to be superior.
