random thing happened to me today...
I was raiding the gardens of eternity and was fighting the second boss when suddenly, one of my healers went backwards to the first boss's place. The other two healers followed trying to heal the first one...
suggestion: try getting the healers to heal multiple raiders , not like all at once, just instead of focusing on one raider until the raider is at full health... cause when i'm fighting the goblin boss, the healers would only heal two other raiders, causing everyone else to die
