Okay, so, I read the thread that wants to nix the puzzles that require more than one person.
While I understand where the poster is coming from, I also agree with a number of poster who responded. I like these things, and I do think they add flavour.
So, here's the thought.
Can we have a warning whenever we are about to enter an adventure that requires a certain minimum of people if we are in a short-handed party?
Example:
Party of 3 comes up to VoN 5, upon entering a warning is displayed: "In order to complete this adventure you need to have 6 people in your party!"
It doesn't keep you from entering, but at least you're warned. (and yes, I know you only need 2 ppl in VoN 5, but that could be left to everyone to figure out on their own. If someone comes to a puzzle and thinks up a way to work it without the game's minimum suggestion, fine.)
I know that this could in a way be considered a spoiler, but on the other hand it really helps shorthanded groups not to waste time on stuff they cannot do. This not only goes for soloers but also for small groups.
