So yesterday, we got a group together and started on the Terrene H3. We had a Mystic and a Warden, all had way over the resolve and health needed. We did the first 3 bosses, perfect. When we got to the 4th boss, Anyena and Yorven, the ones that go back and forth to the statues, We got the strat down, and have completed it before, at least 4 of us. But not the Mystic or Troub, Anyways, nothing that the Mystic would cast, would land on anyone, and I mean nothing not one ward. Heals from the warden were just fine, but not anything from the Mystic. We cancelled everything that ate up wards. We camped to ourselved, the entire group incase it was somehow bugged. We zoned in and out several times. Nothing. When killing statues, healers did not target the tank, they targeted the ones killing the statues. Mystic even targeted himself, and still, nothing even landed on him. Yet everything prior to this worked just fine. Any ideas, on what could be missing or what to check for?
