What I like about the content lockouts is that I now have more free time to do something else.

The most RNG thing I can think of that already exists in this game are the primal and Nightmare mounts. I'm planning to hunt those in pursuit of my tank mount achievements (just to see whether I'd get all 5 mounts before I'd get both my Lion and Bear mounts).

If Coil didn't have a lockout, I wouldn't be able to spend time on that. Or chasing my new master crafters. I'd say a lot of the time I have has been spent on progression trying to learn the fight, as such I haven't found much time to do anything else. So I'm quite glad for the lockouts.
