I had a very good time in the castle last night, and went with a super nice group of folks. We made it to T4, I'm very happy with my prize, and I intend to run again when I can. I know from another thread that the private runs are coming after all the pesky bugs are worked out, but I'd like to make a suggestion for other future puzzley quests...
If the bugs can get squashed ahead of time, I would like to see private runs come first, followed by the public runs... Or private and public released at the same time. This is because, although I surely benefited from some of my co-runners' prior knowledge of some puzzle solutions, I actually would prefer to (attempt to) work out the puzzles on my own. It's totally understandable that a group would be really motivated by the prizes and therefore would power through as fast as possible, but I missed out on a huge swathe of the quest because we had some folks who had been through a time or two before and just pushed forward with me in tow.
All that aside, again, I had a really nice time and my thanks to Vanah for watching out for us!
