The solution is, and will always be a little Speedrun checkbox next to join in progress.
This should force skip cut scenes, and encourage pulling swiftly within reason.
Maybe even reward the group with bonus drops/tomes based on completion time.

You watch how quick all the anti cut scene skipper / anti speed run people are clicking that box and doing it to avoid 8 hour Q times, and reducing the amount of roulette they do weekly.
