I have friends who somehow manage to do this. Not just not playing the beta (that's pretty hard to do) but flat out avoiding any and all news about it. One of them somehow managed not to know anything about the upcoming changes to healing, the CC changes to PvP, even the item squish completely evaded his attention. This isn't just not logging on or anything, it's an act of will, and frankly to my eyes a difficult one. How do you manage it? He even told me he reads various fansites. How do you read fansites and avoid beta news?
Of course, if you're reading this Breakfast Topic, you just failed (since I told you three things from the beta) but perhaps you have some insight. How does one avoid this kind of thing?
