Play a saint. All you have to do is heal, cure and stay alive. No one expects anything else of you and you're vital to the completion of the raid.
If by chance you're not a saint, join a random party. More often than not with how geared everyone is they clear about 60-80% of the time assuming no one screws up too badly.
