Hey.
Was doing RatedBGS yesterday as Guardian and I'm specced into Hibernating Growth which reduce the cast time on my healing touch by 75% if I stay in bear form atleast 10 secs. After the BGs was done I joined a Mythic dungeon run as Resto so I switched my spec and noticed that the buff from guardian spec was still there and the cast time on my Healing Touch was 0.52 sec. Thought it must been something that just stayed there for the moment, went into bear for, cat form and nothing removed the buff. So I went trough with the dungeon and the buff was still present which I noticed fairly much as I was using Healing Touch. When we wiped due to overpulling then buff got removed. I noticed this happens sometimes when I change spec to balance but it only last for one cast. In resto spec I had it all the time.
Is this enlightened by Blizzard? Never seen a post of it here and tried to Google it abit. This might had been used by them tops going for world first if several had this "issue".
