Larisa's got a good rant about something I've considered before in a slightly different context: players aren't very good at anticipating how temporary game changes will work out. We, as a group (not individually necessarily), are quite quick to judgment when we see changes to the game, and the word Larisa uses is "conservatism" -- she notes the examples of the reaction to the zombie outbreak and the Children's Week batleground issues, and says that players "tossed the gift away, like spoiled kids." We (again, in general, not you specifically) have a very short view of how temporary changes will affect the game, lambast Blizzard for changing what didn't need to be changed, and very often, when the dust settles and the zombies are gone or the event is over, we realize that it wasn't so bad after all.
She's not talking about class changes here -- those are more permanent changes that affect the basic rules of the game. But specifically with temporary events (I'd even throw the Brewfest controversies, and the Headless Horseman complaints in the mix), players sometimes have reactions that are way out of proportion to the events themselves. These holidays and world events are temporary: shouldn't we just enjoy them while we can?
It's definitely a valid point, and something to remember for the next time a temporary event throws off your usual routine in-game. The fact is that we players are spoiled -- Blizzard generally does a great job keeping this game fun, and so when even a little issue sneaks into the game during a temporary event. But Larisa promises that next time she gets shaken up by a temporary change, she'll give it another chance. Sounds like a great idea to me.
