Since this came as a surprise to some tanks back in time, maybe add this mention to chain pulling paragraph. There is different mana/health regeneration rate in combat and out of combat, and if tanks chain pull without letting the combat mode end, it ensures a healer who was out of mana, will be out of mana, come next mob. While this is not always an issue, it's good for the tank to be awate of and make note on before charging forward. Especially WHM gets the Shroud fairly late and before that have no real methods to get their mana back.
