Escape from Durnholde Keep

[Flymo]

Do not fear inside the house at Tarren Mill. It causes 3 problems due to mobs running through the house walls:
1) Adds patrolling outside can be aggro'd
2) Thrall can get stuck in a wall, unable to be healed
3) Taretha can despawn

It didn't occur to me to try to heal Thrall. When I did it he tanked the whole quest without any need for healing.

I'd add one more tip for healers: if someone dies during the last encounter (the one outside the house), don't try to resurrect them when out of combat. There isn't quite enough time between waves to complete the spell, and you're better off grabbing a drink.
