[quote who="/b/" reply="1" id="2166230"]Ok my guess goes like this;
If you tell them to attack by right clicking, yes they will pew pew until there target is dead.
If they attack auto closest target, they will heal you as you have not told them to just keep attacking one person.[/quote]
You know, I've noticed that happen as well. If they aren't performing any action you explicitly tell them (including moving, sometimes), they will auto-heal you every 8 seconds. However, move them around and they won't even toss you a heal. This really sucks when you're trying to run away; make sure to stop your priests every now and then so they can keep you topped up.
