I don't know why but I find the beta period incredibly chill. There are no worries. If stuff is broken, I report it. If the content feels weak, I make a forum post saying so. I don't worry about the level ranges for expansion zones, I didn't even get all that worked up over the change to the faction capitals (although I personally didn't like the idea, it didn't work me up). One of the reasons I think I am this way is because, to me, the beta is supposed to be a place where boxes attack me and bears come up out of the ground like sharks to assault me. I expect madness and broken quests and bugginess in my beta experience. It's what the beta is - not just a place where testing can determine what quests are broken, but also a place to roll out content and examine how the experience works.
I don't know. Lately it feels like the forums and twitter have just blown up with ludicrous, over the top negativity for no reason, to the point where a simple tweet about when Tanaan will be released drives players crazy. Yes, stuff is going to change, break, not work right, and not be what you expected. It's the beta. That's how it goes. That's how it's always gone.
