Why do people not understand A8?

Having all mechanics checked is important, but there's no point if DPS is low and you can't meet the light DPS checks. Wiping from enrage in A8 is one of the saddest things since you'll have to start all over again against Onslaught.

I've only seen enrage on it once, and that was my first time in. Low dps was due to deaths, not low dps. Tanks died repeatedly (one attempt MT died about 15 seconds in, before first set of adds), healers were casting raise on tanks while dps were beat on, dps die.
