Civ V multiplayer improved?

My friend and I have tried since Civ V's launch to fully play a game together but suffered constant synchronization problems, dropped games, and unending frustration.

How has people's experience been with the latest expansion? We haven't tried playing Civ V in about a year because of the extent of the issues we experienced even though it is tremendously fun to play multiplayer.

Thanks in advance to anyone with first-hand experience!
