The update gave us a lot of valuable new data and situations to learn from. And one of those is urgent needs for the game to have a larger and more robust server infrastructure. Massive queues, unable to connect, disconnects, regions going offline many times, voice chat problems, and ect...
This is all with just 2,000 - 3,000 players. Nearly everyone is expecting to see far more players then this when the game goes full 1.0 release. Even if it was just doubled the amount as we have gotten, say just 6,000 players. It will be a catastrophe, as there is no way the servers will be able to handle it. There is no way the playstyle of the game can handle it. Hell we're already struggling with just trying to get supplies to the frontlines. As well as the logi hubs are being bottlenecked simply because there are too many players in the back line trying to do logi.
Personally I think this is a major problem, and one the devs should focus on for the next few months.
