@CyberDymeBattlenonesense make some nice videos about this topic:
Dice tested 55hz servers for Xbox One: https://youtu.be/GoZqakBAoHM?t=127 (we now have Xbox Series X/S....)
Battlefield 1 has 120hz servers: https://www.youtube.com/watch?v=BSkPRNXN6e8
And what a higher Tickrate mean for a Battlefield game: https://www.youtube.com/watch?v=7nO9bZm8ceY
The reason why there are so less high tickrate server today is, that they cost more for the community and most admins decide to use 30 or 60 hz for his smale playerbase.
Iam as an customer expect a more advanced product than the previous.
