I never had a game desync and a minidump only once in a while before diplomacy got released. Now i experience desync or minidump in about 20% of my games. Several players online tole me the same, it is almost impossible to have a 5v5 without someone DCing within the first minutes. And I'm not talking about newbs who just quit when they get rushed but veteran players who are no quitters. I have no idea if diplomacy has something to do with these issues, but there is a significant rise in technical problems with entrenchment mp since the beta got released.
