May I add there is no way to present anything so that everyone understands it, I actually didn't know that until Elvenar but it has been proven true over and over. Explain it one way and confuse this person, explain another and confuse this person... the majority of people are apparently just really freaking confused all the time.
I posted a message explaining set buildings, I directed people to all the places they could read about them and see pics and so forth, I re-explained in the chat eleven times, I had multiple one on one conversations about it. I didn't like them, want them or care yet I understood how they worked, had a forum thread going about it before the event started (thanks to sniping a beta post), had already began explaining them in the game before GoK had a page about it. I seriously did everything I could have done except go to peoples houses and do it for them while explaining why I was doing what I was doing and we still have people that got multiple set buildings and have them placed in their city not touching each other at all and trying to figure out what they do!
People are just very good at being confused.
May I add I have been confused once also... once.
(It was a Tuesday at approx. 1pm before the first FA, I was seriously very confused about the 3 paths with 3 switches on 3 pages not knowing there were 3 pages.
3 paths, 3 switches and 3 pages was just to many 3's of things.)
