Yeah, I have yet to have to "not stand in the fire" on mine. I'm sure it'll get more interesting in T1's but leveling instances are, as you mentioned, a complete joke. My warden healer build has a little trouble keeping up with damage on the tank in a few cases, which I'm not sure about yet. Giving some thought to respeccing him to Purifier for better single-target heals, though the HoTs are really nice when I have to move the group or healer as it keeps the healing going.
