I believe there was a quote from a Jmod on twitter, saying that if you die one or two times, your kit chances aren't hardly effected, but after 3+ deaths they become more rare. If you have at least a mediocre tob skill, a good team will be able to carry you and you'll likely only die 2 times or less. If you can't manage to get through the raid consistenly under 2 deaths, then having someone perform the service login or parsec would be more viable
