I don't like speed run if it's a requirement.
I like speed run if it's not a requirement, i.e.: Yaay, we did it in 15 minutes! (Just so we know how well we are doing).

But it should not affect outcome.

This makes it so we are mindless drones having to repeat the exact same clicks in a pre-determined fashion to get to the end in time.

I've reached a point where 'all' I need is only obtainable via speed run. No real incentive to go with friends or pick-up-groups or new people now, other than to teach them or have some general fun. Knowing full well I will get nothing from the chests because it will not be under a certain time limit.
