I just wanna point out that those are not frozen ROAR animations, yes they are not new animations but they are not roaring ones.
Lor'themar is drowning, Sylvanas is mid-air dying, Baine is laughing, Vol'jin is swimming backwards, Thrall is using his explode-into-elementals animation from 4.2, Varian is laughing, Anduin is laughing, Jaina is bowing, Tyrande is shy and Taran Zhu is clapping.
