I see nothing wrong with adding a coil roulette, they need more incentives to run old content not less.

For new players they might luck out and catch a group queuing it for shiggles and if you don't want to run it you can just... not queue for it and problem solved.

While there is the possibility of people avoiding / leaving certain turns it isn't all that different from players bailing on things like AV or SoF anyway.

As mentioned before a raid roulette is long overdue and the content is just stagnating at this point.
