People ask PA for "challenging content". They often want genuine mechanical complexity for their fights. Then PA gives them overdesigned battles that make the servers lag out. I'd be happy with simple, easier content so long as the servers work smoothly.

It's a miracle if I go a full day without seeing that screen. I swear this is the only game I've ever played where crashes are so frequent.

Apart from the crashes, FPS has been getting rough lately. PA has maintained reflex mechanics even as the lag has spiked, which can be frustrating to deal with. It seems as though the servers have a hard time handling all the people who are here at the moment, resulting in players gradually leaving out of frustration with being unable to play the game.

In addtion to reconnects. I've been getting the unstable warning every few hours, sometimes more often, for the last 5 or 6 weeks.

Right now I've just trasitioned from that screen into a reconnecting screen into this... 

Game has been pretty unplayable for a few weeks. And it's not my connection, at least not primarily, because this is not happening with any other game and it's not happening at the same time for other people in my house.

That problem is your ISP 

Not sure why ISPs only seem to have problems with BDO and not other games. BDO needs to do what those other games and internet activities do to have strong connections.
