D2R: PR not Product - 3 days of disconects & disapointment

The game content has been around for years. All you had to do was make it work. Why are there so many issues? Is this a sign of what’s to come from the new Blizzard? If so I’m spending my money on other companies products. Constant disconnects and the game drops mid encounter, when trying to put something in the chest, etc. Whenever I do something I’m worried what will happen next. Is there a fix for this?
