Yeah m/wd hits like a truck, I assume sacredmagic is who XG knows about =). Although to be fair, thunderstorm also doesn't have a cd and it's like an aoe line of sight that allows more flexibilty for areas that you can hit
As I was saying, I think he is more overpowered than priest/scout. M/wd also gets the new briar shield so he has pdef also. Also something that is broken. I can equip curse runes on a talisman. So in siege when Sacred makes a pass at your party I have the talisman equipped. With two curses and a clear thought and an arcane potion I have .3 second urgent heals hitting for 70k on him. When he circles back around (I am in front) I equip shield again. (Can change to shield or talisman mid cast with no cooldown)
