You just displayed perfectly why I don't like running content with couples- "Us against the party". Would you complain if a healer was AFK healing while casting a heal every 10 seconds? I'm sure you would. Would you complain if a DPS wasn't using oGCD abilities, single targeting groups or, and lord knows why, exclusively using AoEs on a boss? I'm sure you would because these are all examples of intentionally poor play. Burdens- like a small pull tank. I understand if it's a tanks first time in a duty, or they aren't that experienced in the game- but let's face it, you're likely neither. This kind of arrogance only comes from experience.
This is a hilarious comeback, bravo.
