The BF4 server Browser was the best feature of the game. We could instantly find any server that catered to our liking. Military could rent servers and have amazing community and fun with the old server Browser system. Finding hardcore servers (which many others and I prefer) was a breeze. Since BF1 seemingly got rid of the server browsing system, many of my friends and family have stopped playing. It disables an easy way to play and communicate together, making the game less enjoyable. The biggest thing I hope to see with BF5 is the return of the server browsing feature we saw in BF4. This will create another amazing game for me and many people I know.
I hope DICE will take into account the wants of the community.
