Here's other reasons. Not wasting ammo or time killing pointless adds. Whoops, there goes that thing called "common sense" again, so silly that. Besides.... if bungies idea of making a fight harder is to add 4 easy to kill knights which serve no purpose other than to annoy, then they have failed at creativity. which deserves to be completely ignored. I could add a few examples from other raids, but it isn't worth the couple KB to transfer it to the website servers.
