The biggest problem with totems is it exposes the weakest player or the not a team player. With people I raid with regularly we all have three rules. Throw grenades at the beginning. Never leave your wing man until the boomers are dead. Kill enemies and wizards while holding power. If all these criteria are met we never wipe. However, we will get a random that will not kill the wizards or leave as soon as they have the power before the boomers are dead. When this happens a mistake will always occur.
