They don't sticky user created threads here, besides, people tend to ignore stickied threads anyway. The problem I noticed is that once the healer pulls aggro from the enemy, it's very hard for a dps to take it away, because healing is much quicker enmity generation than dps. It used to be easily doable, but not in this version anymore. Stunning/sleeping/biting in the ankle is still better than to watch the healer die though
