Ever heard about pre kicks? If the mage on your team blocks or your pally bubbles, its obvious that a good priest will instant MD, you can just pre kick it if you time it right. You don't kick when u see the cast coming, you know it will come and it's a short cast so u kick before he even starts, and with the ms, you will kick when hes already casting. I've seen so many videos of people pre kicking monk's aura mastery (since it's used after u start casting) and making them waste it, same happens with md or soul of the forest...
