This is what you get for forcing them to change their EA plan.
They had the EA phase spread over 3 months for a reason. They do not have the staff nor the resources to handle all those players right away (many might not be aware, but it can take up to 3 months until the money from steam actually arrives at their account).
So all the problems you see now, you should have expected when you voted for the new EA plan.
3 months would have given them more time to provide new servers for each batch of players and it also would have allowed them to slowly work out connection problems and get more staff in time.
so all the crybabies back then, who now even cry louder about bugs and problems: you brought this upon yourself.
