Right now we're still reeling from the aftermath of the disastrous Patch 3.0.8 which received some mixed reactions. Even Hunters, who were supposed to get a nerf, simply re-specced to Survival and went along their merry DPS meter-topping ways. Warlocks were supposed to get a buff, but instead got a bug in the form of a 2-minute cooldown to Ritual of Summoning. Let's not even talk about PvP where Wintergrasp crashed everything and Arenas were disabled because, well, the new undocumented ratings system just plain sucked.
So if there's anything to be thankful for today, it's that it's not a patch day. Not an official one, at any rate. When the servers come up later today, what do expect to find? No more lag? Fixed items? Fixed spells? Or, are you willing to wager -- eating your hat, maybe -- that today's "fix" will only bring more bugs?
Update: Alex here! Silly Zach, today is a patch day! It's a minor patch, bringing us up to v18.104.22.16806. The same questions here all apply, though. What fixes are you hoping to see today? Will game experience improve after today's maintenance?
