Servers issue - suggestion

I saw lot of people write to discord chat they try to connect other servers like Asia,US even if they are from EU.
Its even possible and if yes why dont you just make region lock to stop people change servers every single time connection error or something goes up in game. It make people break servers more by connecting and disconnecting or not ? im not developer but if there will be some kind of region lock and i will be allowed to play only on EUW wich is my region i will be ok with that and i dont need connect to other servers anyway.
It will split playerbase little bit with connections and allow servers breath.
