Practiced it for about 2 hours before I finally got it. So glad I didn't miss the jump into the clock on my first try, dunno if I could've taken it. Since then, though, I've run it a couple more times and now I feel like I'm pretty good at it :D
Looks like no more 10-15 minute CoF runs, at least not running the same path over and over.
On one hand, I think it's fine that Anet wants to stop people from running the same explorable path over and over again. But, on the other hand, armor sets still cost so many tokens that the explorable runs are still necessary, and now those 60+ runs to get the necessary tokens are going to take more time.
