For me, the biggest and most telling sign about how poor the servers are is what's currently happening at 6pm every day.
New content drops, people log in to do packs, check objectives and evos etc... and can't do anything for at least an hour because the traffic can't handle it. Every year without fail this happens during big promos and then again right at the end of the year. They know its coming, they know it happens every time, but they don't care enough to actually do anything about it
I'm sorry but when you're releasing content designed to be recycled and repeated in the menus, but you can't actually do them because you get booted from the servers every time you try, alongside daily play objectives, it's simply just not good enough
