Lifegripping melee that get blasted from mid is like my favorite thing about eots. If I see a mage or shaman moving towards the big ball of melee in the middle I look for who is gonna get knocked closest to me and try to grab them. Isn’t 100% but it always feels good.
On a related note, I had the funniest knock death in a long time in a recent eots. I was on my spriest and mc’d their only healer and was gonna try to run him off the edge. Before I could even try, an evoker on their team used his knockback and sent his own healer flying off the map. There weren’t even any other members of my team near him, he just used his knock only on his own mc’d healer. It definitely made me lol.
