PC: Unable to connect to multiplayer games: "..session lost"

It's been weeks and still no patch for this lost connection issue. Lots of added in multiplayer like not being able to move and no skills upon joining a session. What kind of company is this? Not even an acknowledgement to the issue. They should have tested this before release instead of making the players be beta testers. They also have the nerve to add micro transaction while having an incomplete and broken feature.
