We do with 1x tank 3x rogue. But much easier if you are 2x tank (who are respeced for tanking) and 2x rogue. When im controlling aggro the rogues just concentrate on kills mobs and i hold as much as i can trying not to die. Spamming health pots all the time. Even when im not taking that much DMG due to loss of aggro. Because if tank dies rogues follow shortly after. Just be prepared to use health pots and get as much defence as you can and aggro skills. With 2x tank it is so much easier but still be careful. When those mobs come just hope your rogues know what they are doing always kill crabs first also as they deal most damage! Wouldn't worry about dealing too much damage to boss while mobs are there it's next to impossible just stay alive and once mobs are dead you are free to kill the boss! mobs are th hard part.

I hold both records for cove - pure and elixer.
