Yet to jump into the campaign, keep doing my favorite game mode, 4v4. Not been too bad, haven't had any super weird bugs. Couple times I had to restart client because it said I found a match, but would never actually join it. Nothing major. Biggest problem is that it runs like shit on my gaming laptop. On Low/Medium graphics settings. Also had to turn Vsync on to get rid of insane stutter/tearing. That was the most refreshing part of the old game is that it ran so smooth, and when they added 1080p resolutions that just was icing on the cake.
I hope they respond well to all the uproar, and patch it and do something with it.
