Since our inception, Mistweavers have been a melee healer. In Legion, that's no different. In raids, this classification allows us to go untargeted by some boss abilities, detailed here: http://cranehealing.blogspot.com/2016/0 ... unity.html
This was such a tough concept for people to get when MoP released. I remember being in HoF and my raid leader freaked because I was in with the melee during the Wind Lord Mel'jarak. He was sure I was going to drop wind bombs on everyone LOL
In Siege of Orgrimmar it was particularly annoying for the ranged on Siegecrafter in my raid because they felt they were unfairly targeted while I could just sit and heal away. It's still a tough concept for people to grasp. Hopefully since we are now almost 2 xpacs since the introduction of monks, people will finally learn that we are indeed melee, even as healers.
