Jan 27th 2009 9:10AM Patch 3.0 says hello. Oh I remember that day, server crashes every 10 mins, 10 hour maintainence which stretched out to 30, more lag than you can poke a stick at...
Though admittedly 3.0.8 was fairly poor as well.
Dec 7th 2008 10:22AM Overall, the instances ive done have been less cluttered, and more fun than their TBC counterparts. Something was wrong previously when the only dungeon I liked in TBC was Blood Furnace. Trash is easier than before, but I don't mind that. It is annoying being very precise in pulls, and previously, they caused unnecessary frustration.
Boss fights are so much better , it isn't funny. With a few exceptions, BC 5-man bosses were just no fun. You still get the occasional dissapointing Tank and Spank boss it seems, but nearly all of them are fun.
Blizzard have taken most of the frustrating elements out of instancing and have left the best parts. Generally good boss fights, the instances have much more atmosphere(Halls of Stone and Halls of Lightning are particularly brilliant) and unlike some people have been saying, they aren't TOO easy, a bad group will still fail to make it to the end, one mistake can still wipe the group.
