Sorry but warden do not outheal fury anytime, for example when we do MMIS, the shaman warden nearly cover all incoming damage to the tank even on named. Last time my heal parse was under a pally lol. Whereas doing Emerald hall or freethinker i parse second of the zone behind the defiler and first in a lot of fight. The issue has not changed since KoS. At the start of a tier when things are difficult, warden are very needed because of the amount we can heal. But when fight start to become easy we fall behind and have nothing else than DPS to bring to the raid.
