I'm continually impressed that Wizards manages to keep Magic as balanced and fun as they do, especially considering that they don't have the resources to really playtest formats other than standard. It always makes me angry seeing people in comment threads for previews/spoilers raging about how Wizards is "ruining the game" or some such nonsense. Making Magic is _hard_ and many players don't seem to understand this :( Of course the Magic community is anger-inducing for any number of reasons; but that's another can of worms entirely.
