Their reason that "explorations were always meant to be done that way!" bothered me too. I could understand if the site was new, but it's been that way for years. They suddenly changed it with no real reasoning. I'm still not even sure why. All it's done is made it even more difficult for people to get anything done over there unless they have a lot of free time. Members were complaining about how they miss out on things by not being active, and this makes it even worse.
Yeah, I don't get why we can't share exploration tasks now. It shouldn't matter because it doesn't mean anything. All it would do would tell people the level of difficulty for an exploration so they can tell what they're getting into.
