From time to time, my character will stop attacking and simply cast healing spells. Only if I intervene or if my character dies will it ever do anything else. Even if I intervene and kill a mob, on the next pull, it will do keep healing. However, if my character dies, everything will work correctly again. This process keeps repeating. As you can see in the log, it states that it's casting the healing spell on the mob towards the bottom. The break in there is from me casting spells manually.
