I was a little disappointed upon reaching Wymrest Temple just now to find that Chromie didn't have a quest for me. I had assumed that after I completed 8/8 she would provide another quest offering more Timewarped Badges.
If there aren't anymore quests then I must say I can't really find any reason to do the scenario anymore, which is a shame because I found it really fun and interesting. I was looking forward to running it each week as an extra source of badges. Sure you could farm it for the occasional 10 timewarped badges but I'm not sure that's worth the effort.
As a side note I really enjoyed the challenge of completing 8/8 without everything unlocked, but now that I have the 5th tier trait 'Fortuitous' it's much easier. I'd imagine that unlocking everything would take any remaining challenge out of it. This scenario is a great example of a new and interesting thing added in by Blizzard and I wish they kept it challenging.
