Every other patch, the bug of "EOS/Selene/Pets getting buffed from character's spell speed" keeps coming back, then gets fixed again next patch, then comes back again next patch, and so on. I've seen this happen for the last few patches already.
And as of now, the bug is back.
I can cast rouse then whispering dawn, and my whispering dawn gets cooled down first.
Well, there might be other bugs that keeps coming back, but I've only come across this.
